A standard phonetic grid classifying English consonants by place of articulation, manner of articulation, and voicing status.
Allophones
Different contextual phonetic realizations of the exact same phoneme or grapheme.
Linking r
The pronunciation of a word-final silent /r/ in non-rhotic accents when followed immediately by a word starting with a vowel sound.
Yod Dropping
The omission of the /j/ sound after word-initial alveolar stops (/t, d, n/) followed by /u:/ in General American English.
T-Tapping
A phonetic rule in General American English where an intervocalic /t/ is voiced and articulated almost identically to /d/.

British vs American Pronunciation Variants
Phonetic and stress differences between Received Pronunciation and General American across common vocabulary pairs.
Diphthong
A complex speech sound that starts as one vowel position and glides into another vowel position within the same syllable.
Centering Diphthongs
Diphthongs whose second sound component is the central unstressed schwa vowel /ə/.
Closing Diphthongs
Diphthongs whose second sound component glides toward a close vowel such as /ɪ/ or /ʊ/.
Syllable
A unit of phonological organization composed of one or more phonemes, containing at minimum a single vowel nucleus.

English vs Italian Syllable Structure
A comparative phonological overview showing English preference for closed CVC syllables and consonant clusters versus Italian preference for open CV or V syllables.
Word Stress
The relative acoustic prominence or accentuation assigned to a particular syllable within a word.
Primary Stress
The highest level of prominence in a word, represented in IPA notation by a high vertical line preceding the stressed syllable.
Secondary Stress
A weaker secondary accent on a syllable, represented in IPA notation by a low vertical line preceding the syllable.
Schwa
The central unstressed vowel sound /ə/ commonly found in unstressed syllables and weak forms of function words.
Weak Form
The unstressed and reduced phonetic realization of a grammatical word in normal connected speech.
Strong Form
The full pronunciation of a grammatical word when uttered in isolation or spoken with explicit emphasis.
Coarticulation
The simultaneous or overlapping movement of speech articulators during fast, continuous speech production.
Assimilation
A phonological process in connected speech where a speech sound adapts its phonetic features to match a neighbouring sound.

Retrospective Assimilation of Suffix -s
A rule where the plural, third-person singular, or possessive suffix -s changes its voicing (/z/, /s/, or /ɪz/) based on the preceding consonant sound.
Elision
The disappearance or omission of a speech sound (vowel or consonant) in historical language shift or connected casual speech.

Contextual Elision Examples
Demonstrations of sound omission in spoken phrases driven by articulatory efficiency, such as dropping consonants in clusters.
Homophones
Words that share identical pronunciation but differ in spelling and meaning.
Homographs
Words that share identical spelling but differ in pronunciation and meaning.
Homonyms
Words sharing both spelling and pronunciation that have completely distinct, unrelated meanings and etymologies.
Polysemy
The phenomenon where a single lexeme possesses two or more distinct but semantically related senses.
Lexeme
An abstract unit of lexical meaning underlying a set of related grammatical word-forms.
Denotation
The literal, objective dictionary meaning of a lexeme that links directly to its real-world referent.
Connotation
The subjective, emotional, or stylistic associations attached to a word beyond its literal definition.
Gradable Antonyms

Converse Antonyms
Opposite words that describe a single relationship from two distinct, interdependent perspectives.
Directional Antonyms
Opposite words where one action or trajectory directly undoes or reverses another.
Hyponymy

A grammatical unit of meaning (such as an affix) that must attach to another morpheme.
Allomorph
