Comprehensive Study Guide: Introduction to World Languages, Dialects, Reconstruction, and Field Linguistics
Languages, Dialects, and Accents
Theoretical Definitions of Language vs. Dialect:
Ferdinand de Saussure, in Cours de linguistique générale (1916), defined language as "a product of the collective mind of linguistic groups."
Max Weinreich popularized the geopolitical aphorism: "A language is a dialect with an army and navy."
Geopolitical status often overrides linguistic similarity when determining language status:
Serbo-Croatian was treated as a single language until the early 1990s, after which it split into four distinct standard languages: Serbian, Croatian, Bosnian, and Montenegrin.
Danish, Norwegian, and Swedish are mutually intelligible to a high degree—often referred to collectively by linguists as Mainland Scandinavian—but are classified as three distinct languages due to separate nation-state boundaries.
Norwegian itself comprises two official written varieties: Bokmål and Nynorsk.

Case Study: Scots:
Scots is spoken in the southern and central lowlands of Scotland and sits directly on the boundary between dialect and language status.
Until the Renaissance, English and Scots were the same language, but they gradually diverged until mutual intelligibility became difficult.
Robert Burns wrote famous works in Scots, such as the 1788 song Auld Lang Syne:
"An sheerly yil bee yur pynt-staup! / An sheerly al bee myn! / An will tak a cup of kyndnes yet, / Fir auld lang syne."
Robert Louis Stevenson wrote poetry in Scots, including The Maker to Posterity ("Maker" pronounced "mah-ker" meaning 'poet'):
"No bein fit to write in Greek, / I wrote in Lallans, / Dear to my hert as the peat reek, / Auld as Tantallon."
Lallans (derived from "lowlands") is a traditional name for Scots; Tantallon refers to a mid-14th-century castle overlooking the Firth of Forth.
A defining sound feature of Scots is the merger of vowels in words like pin and pen (both pronounced as pen), causing fit to sound identical to fête.
Geopolitical Models vs. Multilingual Nations:
The one-language-one-country model fails in highly multilingual regions:
Belgium contains four linguistic zones: Dutch/Flemish in the north, French/Walloon in the south, German in the east, and the bilingual capital of Brussels.
Switzerland contains four linguistic zones: French in the west, German in the north and center, Italian in the southeast, and Romansch in the east.
Extreme linguistic diversity exists globally: Nigeria has 527 distinct languages, Indonesia has 715, and Papua New Guinea has 840.
Mutual Intelligibility Criteria and Structural Limitations:
Linguists use mutual intelligibility as the primary criterion: varieties that are mutually intelligible are dialects of the same language; varieties that are not are distinct languages.
Limitations of the mutual intelligibility standard:
Intelligibility varies by topic, context, and phrasing.
Perception is subjective: non-speakers notice similarities, whereas native speakers focus on differences.
Intelligibility can be asymmetrical due to differential exposure (e.g., Ukrainian speakers understand Russian easily, but Russian speakers unexposed to Ukrainian understand very little).
Comparing text snippets tests surface outputs rather than underlying cognitive rule systems.


Structural Analysis of Word Order Differences (English vs. Norwegian):
Sentence 1: English We shall sing tomorrow vs. Norwegian Vi skal synge i morgen. Both follow Subject-Auxiliary-Verb-Adverb order.
Sentence 2: English Tomorrow we shall sing vs. Norwegian I morgen skal vi synge.
In English, fronting the adverb Tomorrow leaves the auxiliary verb shall after the subject we (Subject-Auxiliary order).
In Norwegian, fronting the adverb I morgen forces the auxiliary verb skal into the second structural position, pushing the subject vi to the third position. This rule is called Verb-Second (V2).
Dialect Continua and Isoglosses:
A dialect continuum is a continuous geographic range of local dialects where adjacent varieties are mutually intelligible, but varieties at extreme ends are mutually unintelligible.
Continental West Germanic Dialect Continuum:
Encompasses High German (spoken in Swiss German regions, Austria, Munich, Nuremberg), Middle German (Frankfurt-am-Main, Cologne, Dresden), Low German (Bremen, Lübeck, Kiel), Dutch, and Flemish.
A traveler going from Bern to Bruges encounters smooth local transitions, yet speakers from the endpoints cannot understand each other in local varieties.
Benrath Line (machen-maken line):
Isogloss dividing Low German/Dutch stop consonants (maken, dat, dorp) from High German fricative consonants (machen, das, dorf).
Cognates of dorp/dorf appear in English place names like Mablethorpe and Scunthorpe in Lincolnshire.
Other Dialect Continua: Western Romance (Portugal, Spain, France, Italy), East Slavic (Russian, Belarusian, Rusyn, Ukrainian), South Slavic (Slovenian, Croatian, Bosnian, Serbian, Macedonian, Bulgarian), Persian, Turkic, Arabic, Algonquian (Alberta to Labrador), and Eskimo-Aleut (Alaska and Northern Canada).
Isogloss: A line on a map marking the geographical boundary of a specific linguistic feature. Bundles of isoglosses define dialect boundaries.
Accents vs. Dialects:
Dialects differ across pronunciation, vocabulary, and grammar.
Accents differ exclusively in pronunciation.
Scouse (Liverpool Accent) Characteristics:
Pronouncing words like strut, much, but, lucky, us, month, rub with the high back rounded lax vowel , matching bull, foot, put.
Pronouncing vowels in had, that, laugh, stand, last with the tongue backed (shared with Glasgow/Scottish English).
Pronouncing words like work, personal, stir, nurse with a long version of the vowel in pet, ten, set or , spoken with spread lips.
Final in short function words (not, that, what) replaced by or glottal stop .
Non-final pronounced as in words like two and about.
Post-vocalic lenition (spirantization): Stop becomes velar fricative after non-front vowels (back , walk ), and palatal fricative after high front vowels or diphthongs (week, like, bike, chicken).
Parallel in Biblical Hebrew post-vocalic lenition: 'queen' vs. 'king' ; Modern Hebrew 'star' vs. 'to star' .
Geordie (Newcastle Dialect) Characteristics:
Uses in love.
Double modal verbs (She might could come tomorrow).
Uses past tense forms in place of past participles (I've took it, You done it, did you?).
Phonetic Vowel Classification Dimensions:
Back/Front: Tongue horizontal position ( in feel is front; in fool is back).
High/Mid/Low: Tongue/jaw vertical height ( in bid is high; in bed is mid; in bad is low).
Rounded/Unrounded: Lip posture ( in fool is rounded; in feel is unrounded).
Oral/Nasal: Velum posture ( in back is oral; in bank is nasalized).
Tense/Lax: Vocal tract muscle tension ( in feel is tense; in fill is lax).
Language Families and Relationships
Concepts of Family Trees and Proto-Languages:
Related languages descend from a single ancestral Proto-Language.
Unlike human families, languages do not marry, nor do they descend from two separate parent languages ("mom" and "dad").
Subfamilies/Branches of Germanic:
West Germanic (Proto-West-Germanic ancestor): English, Dutch, German, Frisian.
North Germanic: Old Norse ancestor (Swedish, Norwegian, Danish, Icelandic, Faroese).
East Germanic: Extinct branch.

Germanic Structural Characteristics:
Verb-Second (V2) Word Order:

* Dutch: *Gisteren las ik dit boek.* ('Yesterday, I read the book.')
* German: *Gestern las ich dieses Buch.* ('Yesterday, I read the book.')
* Swedish: *Igår läste jag denna bok.* ('Yesterday, I read the book.')
* English is the only Germanic language that lost general V2, shifting to SVO/V3 order (*Yesterday I read the book*).
* Residual V2 in Modern English occurs after negative adverbs or *only*: *Never have I heard about the V2 pattern!* / *Only under certain circumstances would a verb precede a subject in English.*
* Non-Germanic V2 languages: Rhaeto-Romance (Romance), Breton (Celtic), Sorbian (Slavic), Kashmiri (Indo-Aryan).
Cognates across Germanic Languages:

* English *apple*, German *Apfel*, Dutch *appel*, (West) Frisian *apel*, Norwegian (Bokmål) *eple*, Swedish *äpple*.
* English *book*, German *Buch*, Dutch *boek*, (West) Frisian *boek*, Norwegian *bok*, Swedish *bok*.
* English *brown*, German *braun*, Dutch *bruin*, (West) Frisian *brún*, Norwegian *brun*, Swedish *brun*.
* English *give*, German *geben*, Dutch *geven*, (West) Frisian *jaan*, Norwegian *gi*, Swedish *ge*.
* English *hand*, German *Hand*, Dutch *hand*, (West) Frisian *hen*, Norwegian *hånd*, Swedish *hand*.
* English *two*, German *zwei*, Dutch *twee*, (West) Frisian *twa*, Norwegian *to*, Swedish *två*.
* English *that*, German *das*, Dutch *dat*, (West) Frisian *dat*, Norwegian *det*, Swedish *det*.
Grammatical and Prosodic Germanic Traits:
Two-way tense system (present and past).
Past tense formation via suffix (-ed in English; -et, -de, -te, -dde in Norwegian) or root vowel alteration (ablaut: sing/sang, gå/gikk, ligge/lå).
Word-initial stress rule (non-initial stress in English stems from loanwords like Russian perestroika or French chandelier).
External influences on English: Celtic substratum (pre-400s CE) and Norman French superstratum (post-1066 CE).
Language Isolates:
Languages with no demonstrable genetic relationship to any known language family.
Basque: 750,000 first-language speakers in the Basque Country of Spain and France.
Burushaski: 112,000 speakers in northern Pakistan.
Comparative Reconstruction
Methodological Principles:
Comparative reconstruction compares corresponding forms across candidate languages to reconstruct lost proto-language forms and establish family structures.
Relies on systematic regular sound correspondences rather than surface phonetic identity.
Sound changes can obscure cognates: French feuille and Spanish hoja both derive from Latin folia, despite sharing no consonants due to regular sound changes ( in Spanish: fils/hijo, farine/harina).
Distinguishing Cognates from False Friends and Loanwords:
Semantic Drift in True Cognates:
English dish vs. German Tisch ('table').
English starve vs. German sterben ('to die').
English knight (elevated rank) vs. German Knecht ('servant'); German Ritter ('knight') is cognate with English rider.
English loaf (Old English hlāf 'bread') vs. Russian xleb ('bread').
False Friends: Words that sound similar but derive from completely different roots:
Italian strano ('strange', from Latin extraneus) vs. Russian strannyj ('strange', from strana 'country').
Unrelated superficial lookalikes: English men vs. German Mähne ('mane'), Lithuanian mėnuo ('month'), Sanskrit men-ā ('female, doe'), Turkish men ('prohibition'), Hungarian mén ('stallion').
Numeral Cognates across Eurasian Languages:

Cognate series (Indo-European): Irish (aon, do, tri…), Greek (hen, duo, treis…), Latin (unus, duo, trēs…), Italian (uno, due, tre…), French (un, deux, trois…), English (one, two, three…), German (ein, zwei, drei…), Swedish (en, två, tre…), Russian (odin, dva, tri…), Bengali (ek, dvi, tin…), Persian (yak, do, se…).
Non-cognate series: Turkish (bir, iki, üç…), Hebrew ('exad, šnaim, šloša…), Malay (satu, dua, tiga…), Mandarin Chinese (yi, er, san…).
Regular Sound Correspondences and Directionality of Change:

Correspondence Set: Initial in English, Latin, and Old Irish corresponds to in Ancient Greek:
English six, Latin sex, Greek hex, Irish se.
English seven, Latin septem, Greek hepta, Irish seacht.
English salt, Latin sal, Greek hals, Irish salann.
English sow, Latin sūs, Greek hūs, Irish socc.
Latin/Greek loanword doublets in English: semi- / hemi-, sal / hals (halite, halogen), sol / helios, somnus / hypnos.
Principles of Directionality (Lenition and Palatalization):
Sound changes move unidirectionally from articulated forms to relaxed forms (lenition).
Alveolar fricative requires precise tongue placement on the alveolar ridge; glottal fricative requires no oral obstruction.
is a standard unidirectional lenition process; does not occur naturally.
Reconstructed Proto-Indo-European had , retained in Latin, Irish, and English, but innovated to in Greek.

Polynesian Sound Correspondences:
Māori ihu ('nose'), hau ('dew'), hiku ('tail').
Tongan ihu, hau, hiku.
Samoan isu, sau, si'u.
Hawaiian ihu, hau, hi'u.
Samoan retains Proto-Polynesian , while Māori, Tongan, and Hawaiian underwent lenition.
Shared Innovations vs. Shared Retentions:
Subgroups in family trees must be established using shared innovations, not shared retentions.
Shared retention of in Latin, Irish, and English does NOT prove a special subgrouping; it is merely an inherited primitive trait.
Shared innovation of in Māori, Tongan, and Hawaiian proves a valid Polynesian subgroup excluding Samoan.
Centum vs. Satem Split in Indo-European:
Centum languages (Romance, Germanic, Celtic, Tocharian) retain original PIE velar (e.g., Latin centum).
Satem languages (Balto-Slavic, Indo-Iranian) reflect a shared palatalization innovation or (e.g., Avestan satem).
Discovery of Tocharian in western China proved Centum is a geographic retention rather than a single eastern/western branch.
Reconstruction of Proto-Indo-European Nominal Case Inflection:

Reconstructed Proto-Indo-European case forms for 'wolf' ():
Nominative: (Sanskrit vṛk-as, Russian volk, Lithuanian vilk-as).
Vocative: (Sanskrit vṛk-a, Russian —, Lithuanian vilk-e).
Accusative: (Sanskrit vṛk-am, Russian volk-a, Lithuanian vilk-ą).
Genitive: (Sanskrit vṛk-asya, Russian volk-a, Lithuanian vilk-o).
Ablative: (Sanskrit vṛk-ad, Russian —, Lithuanian —).
Dative: (Sanskrit vṛk-aya, Russian volk-u, Lithuanian vilk-ui).
Locative: (Sanskrit vṛk-e, Russian volk-e, Lithuanian vilk-e).
Instrumental: *w\underset{\circ}{l}k^w\text{-\bar{o}} (Sanskrit vṛk-a, Russian volk-om, Lithuanian vilk-u).
Asterisks () denote non-attested, scientifically reconstructed forms.
Lithuanian denotes historical nasal vowel , descending from PIE accusative suffix .
Global Linguistic Diversity and Language Endangerment
Quantitative Estimates and Global Distribution:
Approximately 7,151 living languages are cataloged in Ethnologue.
Recent additions stem from re-evaluations, newly documented languages (e.g., Cuba with 6,000 speakers in Nigeria, Baazəm with 450 speakers in Nigeria, Ulterior Mixe in Mexico, Yilan Creole Japanese in Taiwan), and village sign languages (Kata Kolok in Bali, Adamorobe, San Juan Quiahije Chatino).
Extreme skewness in speaker distribution:
23 languages account for over half of the world's population.
Mandarin Chinese has nearly 1 billion speakers.
The median global language size is approximately 7,500 speakers.
Asian and European languages are spoken by 85% of the human population.
Two-thirds of all languages are concentrated in Africa and Asia.
Largest Language Families by Language Count:
Niger-Congo: >1,500 languages.
Austronesian: >1,200 languages.
Trans-New Guinea: >450 languages.
Indo-European: 447 languages (#1 in total speaker count at ~3.3 billion).
Population Size vs. Language Endangerment Factors:
Language size alone does not dictate endangerment status.
Small Vulnerable Languages: Gurrgoni (Australia, 46 speakers), Awera (Indonesia, 70 speakers), Itik (Indonesia, 80 speakers).
Small Critically Endangered Languages: Itelmen (Russia, 100 speakers), Amur Manchu (Russia, 10 speakers), Bikya (Cameroon, 1 speaker).
Moderate Endangered Languages: Cabécar (Costa Rica, 8,800 speakers), Awa Cuaiquer (Colombia/Ecuador, 13,000 speakers), Lishana Deni (Israel, 7,500 speakers).
Large Endangered Languages:
South Italian: Vulnerable, 5.7 million speakers.
Low Saxon: Vulnerable, 6.7 million speakers.
Belarusian: Vulnerable, 5.1 million speakers.
Sicilian: Vulnerable, 4.7 million speakers.
Lombard: Definitely endangered, 3.9 million speakers.
Venetan: Vulnerable, 3.9 million speakers.
Gondi: Vulnerable, 3 million speakers in India.
Zazaki: Vulnerable, 1.6 million speakers in Turkey.
Yiddish: Vulnerable, 1.5 million speakers.
Romani: Vulnerable, 1.5 million speakers.
Emilian: Vulnerable, 1.3 million speakers.
Limburgian-Ripuarian: Vulnerable, 1.3 million speakers.
Picard: Severely endangered, 700,000 speakers in France.
Provençal: Critically endangered, 350,000 speakers in France.
Mechanisms of Language Diversification
Drivers of Linguistic Divergence:
Extra-linguistic factors: geographical migration, physical or social isolation, substrate/superstrate contact, historical contingencies.
Language-internal factors: structural rebalancing of phonological systems.
Case Study: Evolution of English:
Anglo-Saxon migration to the British Isles provided geographic separation from continental West Germanic.
Contact with indigenous Celtic speakers, Scandinavian Vikings (Old Norse), and Norman French elites after 1066 CE.
Post-Black Death mass internal migration to southern England mixed regional dialects, triggering the Great Vowel Shift.
Explains orthographic doublets: sea vs. see were pronounced distinctly before the Great Vowel Shift.
Case Study: Diversification of Romance Languages:
Leaders of the First Crusade (1096–1099 CE)—Godfrey of Bouillon, Raymond of Toulouse, Robert of Flanders, and Bohemond of Tarantola—spoke mutually intelligible early Romance varieties ("lingua franca" or "language of the Franks").
Accumulation of distinct innovations created modern Romance languages:
North Gallo-Romance selected donare ('to give', French donner) over dare.
Loss of final vowels in North Gallo-Romance: French quand vs. Italian quando and Spanish cuando.
Greek borrowing kata ('each') was adopted in Gallo-Romance and Ibero-Romance (French chaque, Spanish/Portuguese cada), but Italo-Romance developed ogni (from Latin omnem).
Verb *parabolare ('to speak') adopted in Gallo-Romance and Italo-Romance (French parler, Italian parlare), whereas Ibero-Romance adopted *fabulare (Spanish hablar, Portuguese falar).
All three adopted sapere ('to know').
Non-Migratory Diversification Mechanisms:
Dialectal fragmentation of Irish Gaelic via geographical isolation of rural villages.
Middle English (1066 to late 1300s): Extreme regional dialectal variation occurred because peasantry remained localized while governing classes spoke Norman French.
Sign Languages
Structural and Cognitive Status:
Natural sign languages possess fully developed grammatical systems identical in complexity and rule-governed structure to spoken languages.
Emerge spontaneously whenever Deaf individuals form regular communicative communities.
Emergence of Nicaraguan Sign Language (NSL):
Primary school for the Deaf opened in 1980 in Nicaragua focusing on lip-reading.
Deaf children combined home gestures into a pidgin ("homesign") lacking consistent grammar.
Younger children exposed to the pidgin standardized it and introduced grammatical devices, creating a full natural language.
Ethnologue lists over 140 cataloged sign languages.
Categorization: Emergent sign languages (e.g., NSL, Al-Sayyid Bedouin Sign Language) vs. Established national sign languages (e.g., British Sign Language [BSL], American Sign Language [ASL]).
Iconicity vs. Arbitrariness:
Some signs feature iconic visual motivation (BSL: HOUSE, COME, NEAR; ASL: BIRD, DRIVE, DRINK).
Most signs are completely arbitrary (e.g., BSL 'sister' signed as a bent index finger touching the nose).
Cross-linguistic variation for identical meanings:
'Woman': BSL = index finger stroking right cheek; Swedish Sign Language (SSL) = cupped hand on chest; ASL = thumb-tip touching chin then chest.
Homogeneous signs with divergent meanings across sign languages:
Beard gesture: ASL = 'old'; BSL = 'man'.
BSL 'true' = ASL 'stop' = SSL 'right/correct'.
BSL 'good' / 'bad' = Japanese Sign Language 'male' / 'female'.
Structural Independence from Spoken Languages:
Vocabulary non-equivalence: One BSL sign can mean 'pain', 'expensive', or 'Brighton' depending on context; two distinct BSL signs translate the English verb 'read' based on object type (book vs. notice).
Syntax: English follows strict SVO word order, whereas BSL syntax is non-SVO and subject/object pronouns are often omitted.
Phonology in Sign Languages (William Stokoe, 1960s):
Built on meaningless, contrastive parameters: Handshape, Location, Movement, and Hand Orientation.
Minimal Pairs in ASL:
Handshape contrast: SCHOOL vs. IMPOSSIBLE; POSSIBLE vs. DYE.
Location contrast: APPLE (mouth level) vs. ONION (eye level); THINK (forehead) vs. DISAPPOINT (chin); SUMMER, UGLY, DRY form a minimal triplet.
Movement contrast: AIRPLANE (repeated movement) vs. FLY (single movement).
Hand Orientation contrast: BALANCE (palm upward) vs. MAYBE (palm downward).
Sign Language Genealogy and History:
Sign languages do not share genetic relationships with coterritorial spoken languages.
ASL is descended from Old French Sign Language (attested ~300 years ago; ~40% shared cognates with modern French Sign Language).
ASL relatives: Dutch Sign Language (NGT), Republic of Ireland Sign Language (ROISL), Quebec Sign Language (QSL), Spanish Sign Language. ASL was brought to North America by Thomas Hopkins Gallaudet in the early 1800s and influenced by Plains Indigenous Sign Language. Used by 300,000–500,000 signers in the USA and Canada.
BSL, Australian Sign Language (Auslan), and New Zealand Sign Language (NZSL) form the separate BANZSL family.
Structural contrasts between ASL and BSL:
WHERE: BSL uses two hands palms up; ASL uses one hand index finger up.
OK: BSL uses thumb up; ASL uses fingerspelled O-K.
PIG: BSL mimics snout shape; ASL mimics eating from a trough.
DEAF: ASL touches ear then mouth with index finger; BSL touches ear then mouth with index and middle finger together.
VERY HARD OF HEARING: ASL means 'almost deaf'; BSL means 'almost hearing person'.
Field Linguistics and Language Documentation
Scope, Rationale, and Imperative:
Language documentation aims to produce representative corpora and structural analyses of human languages.
Urgency: Over 50% of living languages are endangered. As of 2016, 38.7% of endangered languages and 42% of non-endangered languages lacked published grammatical descriptions.
Documentation is essential for building empirical foundations for linguistic typology, universal grammar, and cognitive science.
Methodological Fieldwork Procedures:
In-situ research isolates village-level language patterns from diaspora contact noise or individual speaker idiolects.
Methodological progression:
Identification and analysis of phonetic and phonological systems.
Compilation of lexicographical descriptions (dictionaries).
Syntactic and semantic analysis.
Descriptive/Typological Linguists (D-linguists) focus on comprehensive grammatical descriptions, whereas Theoretical Linguists (C-linguists) investigate specific structural phenomena.
Native-speaker community linguists ("insider" research) work alongside external linguists in integrated field stations, such as the University of Maryland Guatemala Field Station (studying Mayan languages like Kaqchikel).
Discoveries Originating from Fieldwork:
Empirical acquisition patterns of ergativity across diverse language families (Bavin & Stoll 2013).
Children acquiring complex polysynthetic morphology in Inuit (Allen 2017), Mayan languages (Mateo Pedro 2015, Pye 2017), Murrinhpatha (Forshaw et al. 2017), and Chintang (Stoll et al. 2017).
Processing mechanisms of typologically rare structures (Norcliffe et al. 2015, Sauppe 2017).
Sociolinguistic variation dynamics in small communities (Stanford 2009).
Emergence of novel auxiliary structures in Light Warlpiri through hybrid merging of Kriol and Warlpiri (O'Shannessy 2013).
