Elision

Elision is the omission of a sound — a phoneme or an entire syllable — in connected speech. Where Assimilation changes a sound, elision removes it entirely. It is one of the primary mechanisms by which English compresses unstressed material to maintain its stress-timed Rhythm.

Common Patterns

Loss of /t/ and /d/ in consonant clusters — the most frequent and systematic type of elision in English. When /t/ or /d/ appears between two other consonants, it is regularly dropped:

• "next day" → /neks deɪ/
• "last night" → /lɑːs naɪt/
• "mashed potato" → /mæʃ pəteɪtəʊ/
• "world cup" → /wɜːl kʌp/
• "old man" → /əʊl mæn/

The conditioning environment is clear: three consonants in sequence are articulatorily expensive, so the middle plosive is sacrificed. This rule applies across word boundaries and within words.

Syllable reduction in polysyllabic words — unstressed syllables collapse or disappear:

• "comfortable" → /kʌmftəbl/ (4 syllables → 3)
• "library" → /laɪbri/ (3 → 2)
• "temperature" → /temprətʃə/ (4 → 3)
• "chocolate" → /tʃɒklət/ (3 → 2)
• "vegetable" → /vedʒtəbl/ (4 → 3)

Elision of /h/ — the initial /h/ of unstressed pronouns and auxiliaries is routinely dropped: "tell him" → /tel ɪm/, "what has he" → /wɒt əz i/. The /h/ is retained only when the word is stressed or utterance-initial.

Elision of /v/ — "of" reduces to /ə/ in fast speech: "cup of tea" → /kʌpə tiː/. "Have" as an auxiliary loses /h/ and sometimes /v/: "I should have" → /aɪ ʃʊdə/.

What Governs Elision

Elision is not random. It follows phonotactic and prosodic constraints:

• It targets sounds in unstressed positions, particularly weak syllables
• It simplifies consonant clusters that exceed the language's preferred complexity
• It occurs more in fast, informal speech and in high-frequency phrases
• It is blocked where removing the sound would create ambiguity or violate phonotactic rules

Teaching Implications

Receptive first. Elision is the reason learners say "I know all the words but I can't understand native speakers." Training learners to expect elision transforms their listening. Activities: dictation at natural speed, gap-fill with elided forms, minimal pair exercises contrasting careful vs. natural pronunciation.

Production follows naturally. Drilling specific high-frequency chunks with their elided forms — "I don't know" /aɪ dəʊn nəʊ/, "want to go" /wɒnə gəʊ/ — is more effective than teaching elision rules in the abstract. As fluency develops and speech rate increases, learners begin eliding naturally because the articulatory pressure is the same for all speakers.

Elision often co-occurs with Assimilation and Linking. In "handbag," /d/ is elided and /n/ assimilates to /m/. In "next one," /t/ is elided and /s/ links to the following vowel. These processes work as a system, all driven by the stress-timed Rhythm of English.
