  • Derivational Morphology

What is Morphology?

  • Definition: Morphology is the component of grammar that deals with words and word formation.

  • Words can either be simple or complex.

  • Language differences affect how words are constructed.

  • New words are created continuously by speakers, meaning no dictionary can remain entirely current.

What is a Word?

  • Definition of a Word: A word is defined linguistically as the smallest free form in a language.

  • A free form is an element that can be ordered freely and can occur on its own without being attached to another element.

Example of Word Count:

  • Sentence: "Dinosaurs are extinct."

  • Analysis: The sentence consists of 3 words, specifically the free forms:

    • dinosaurs

    • are

    • extinct

  • However, the ending -s in "dinosaurs" is not a free form, as it cannot stand alone and must attach to "dinosaur." It adds meaning by indicating plural.

Morphemes

  • Definition: A morpheme is the smallest unit of language that carries meaning or serves a function.

  • Example:

    • The word dinosaurs contains two morphemes:

      • dinosaur (the root, meaning a prehistoric creature)

      • -s (indicating the plural form; more than one)

  • Combination: The morphemes combine to form the single word "dinosaurs."

Counting Morphemes in Words


  • Example words and their morpheme counts:

    Word

    Number of Morphemes


    build

    1


    builder

    2


    builders

    3


    act

    1


    active

    2


    activate

    3


    reactivate

    Simple vs. Complex Words

    • Simple Words: Consist of one morpheme (e.g., build, train, act).

    • Complex Words: Consist of more than one morpheme (e.g., builder, builders, trains, active, activate, reactivate).

    Types of Morphemes

    • Free Morpheme: A morpheme that can stand alone. Example: dinosaur is a free morpheme.

    • Bound Morpheme: A morpheme that must be attached to another element to convey meaning (e.g., -s indicating plural).

    Language Variation in Morphemes

    • Languages differ in which morphemes are classified as free or bound.

    • Example: In the Hare language (an Indigenous language spoken in Canada), body part words require possession and cannot stand alone, making them bound morphemes.

      • Examples of grammatical vs. ungrammatical forms:

        • (head) - ungrammatical without possessor

        • sefí (my head) - grammatical with possessor

    Example Summary:
    • Bound Morphemes in Hare:

      • (belly)

      • nebé (your belly)

      • dzé (heart)

      • ʔedzé (someone’s heart/a heart)

    Thai Language Morphemes

    • In Thai, the past tense is expressed using a free morpheme, demonstrating the difference from English morphology.

      • Example: "Boon thaan khaaw lɛɛw" (Boon eat rice past) vs. English: "Boon ate rice."

    Allomorphs

    • Definition: Allomorphs are variants of a morpheme.

    • Example of allomorph of the morpheme a /æ/:

      • Possible Variants:

        • [æ] in the environment before a consonant (e.g., a building)

        • [æn] in the environment before a vowel (e.g., an orange).

    English Plural Allomorph /-s/


    • The plural morpheme /-s/ has multiple allomorphs based on phonological environment:

      Word

      IPA Transcription of Plural

      Environmental Context


      cats

      [kæts]

      After voiceless consonant


      dogs

      [dɔgz]

      After voiced consonant


      judges

      [dʒʌdʒəz]

      After affricate consonant


      hats

      [hæts]

      After voiceless consonant


      heads

      [hɛdz]

      After voiced consonant

      Word Structure

      • Complex words typically consist of a root and one or more affixes.

        • Root: The morpheme containing the major component of the word’s meaning that belongs to a lexical category (noun, verb, etc.).

        • Affix: A morpheme that does not belong to a lexical category and is always bound (e.g., prefixes and suffixes).

      Lexical Categories of Roots

      • All roots with substantial meaning belong to a lexical category:

        • Nouns: Refer to people/things. Examples: citizen, tree, intelligence.

        • Verbs: Usually denote actions or states. Examples: depart, teach, melt, remain.

        • Adjectives: Typically refer to properties. Examples: nice, red, tall.

        • Prepositions: Refer to spatial relations. Examples: in, near, under.

      Identifying Roots and Affixes

      • To determine the lexical category of a root, also note the function of the affixes.

        • Example: The verb teach combines with the affix -er to form teacher, indicating someone who teaches.

      Drawing Word Trees

      • Word Trees: Visual representation of word structure, identifying roots and affixes.

      • Example structures for words:

        • unkind → un-kind (Af-A)

        • blacken → black-en (root + Af)

        • books → book-s (root + Af)

        • destroyed → destroy-ed (root + Af)

      Bases in Affixation

      • Definition of Base: The form to which an affix is added. For words with two morphemes, the base is equivalent to the root.

        • Example: black-en, where black is the base for -en.

      • When more than two morphemes are involved, the base can consist of the root plus any previous morphemes added.

        • Example: blacken-ed, where blacken is the base for -ed.

      Types of Affixes

      • Prefixes: Affixes added to the front of the base. Example: re-, in-.

      • Suffixes: Affixes added to the end of the base. Example: -ful, -ment.

      • Infixes: Affixes inserted within another morpheme. These are rarer in English. Example: expletive infixation in fan-f***ing-tastic.

      Infixation in Other Languages

      • In Tagalog, the infix -in- indicates completed events, unlike English where infixation is much less common.

      • Example:

        • Base: bili (buy) → binili (bought).

        • Base: basa (read) → binasa (read in past tense).

      Non-Concatenative Morphology

      • Non-concatenative morphology is a pattern where words are not constructed linearly by adding prefixes and/or suffixes.

      • In contrast, concatenative morphology is typical in English and involves constructing words by combining roots with prefixes and suffixes.

      Morpheme-Based vs. Word-Based Languages

      • Word-Based Languages: Most complex words are built from free morphemes that can stand alone (e.g., English).

      • Morpheme-Based Languages: Require morphemes to be bound, even roots. Examples include Spanish and Japanese, where verb roots must have affixes to be used as words.

        • Spanish Examples:

          • camin-ó (walk-PAST)

          • escuch-ó (listen-PAST)

          • limpi-ó (wipe-PAST)

        • Japanese Examples:

          • arui-ta (walk-PAST)

          • kii-ta (listen-PAST)

      Special Cases in English Morphology

      • Some English roots behave like bound morphemes and require affixes to be pronounced as words:

        • unkempt, inept do not stand alone as independent words.

        • Roots can arise through language change, like kempt which was once a free root in older forms of English.

      Non-Transparent Morphology

      • Words that do not have transparent morphology and must be analyzed as single morphemes:

        • Examples: receive, deceive, conceive, perceive; permit, submit, commit

      • These words were borrowed from Latin/French, making their morphology non-transparent in English.

      Derivation

      • Definition: Derivation occurs when the addition of an affix changes the meaning and/or lexical category of the base.

        • Examples illustrating verbal bases to noun derivatives:

          • sellseller (one who sells)

          • writewriter (one who writes)

          • teachteacher (one who teaches)

          • singsinger (one who sings)

          • thinkthinker (one who thinks)

      Additional Examples of Derivation

      • Examples of words formed through derivation:

        • treatment (noun from verb treat)

        • unwise (adjective from wise)

        • seasonal (adjective from season)

        • modernize (verb from modern)

      Drawing Tree Structures for Derived Words

      • Tree structures illustrate how each derived word is composed of its morphemes.

        • For example:

          • treatment:

            • Derived noun treatment.

          • unwise:

            • Derived adjective unwise.

          • seasonal:

            • Derived adjective seasonal.

          • modernize:

            • Derived verb modernize.

      Constraints and Restrictions in Derivation

      • Sometimes derivation is constrained by the origin of the word. Some suffixes can only combine with Latin-derived bases, e.g., –ant in words like assistant and combatant.

      • Avoidance of new derivations of existing words is called blocking. Examples include:

        • cooker is blocked by cook.

        • famosity is blocked by fame.

      Phonological Constraints on Derivation

      • Suffixes such as -en have specific phonological rules defining their compatibility with base words.

        • The base must typically be:

          • Monosyllabic

          • Ending with consonants other than /l, r, m, n, ŋ/

        • Acceptable Examples:

          • whiten

          • soften

          • madden

          • quicken

        • Unacceptable Examples:

          • abstracten (base is 2 syllables)

          • angryen (base ends in a vowel)

      Summary

      • Morphology encompasses the study of words and word structure.

      • Words can be categorized as simple or complex and breakdown into smaller units known as morphemes.

      • Certain morphemes are classified as free, while others are bound; language variation affects these classifications.

      • Complex words comprise a root alongside one or more affixes (prefixes, suffixes, and infixes).

      • Roots possess substantial meanings and adhere to specific lexical categories.

      • Derivational processes can alter the meaning or category of the base and are subject to various constraints.
