Definition:
Elision is the omission of a speech sound — a vowel, consonant, or whole syllable — in natural, connected speech. It occurs because rapid speech with overlapping articulatory movements makes certain sounds optional or phonetically unnecessary for comprehension. Elision is found in all languages and is most extensive in informal, rapid speech. For language learners, elision is one of the primary sources of listening comprehension difficulty: learners who know only citation (dictionary) pronunciations may fail to recognize words when sounds are elided.
Types of Elision
Vowel elision:
Unstressed vowels are frequently elided in rapid speech:
- English: police ? often [pli?s] (unstressed /?/ deleted); family ? often [fæmli] (middle syllable reduced)
- French: élision — the formal deletion of final vowel before initial vowel in next word: la amie ? l’amie (obligatory in French spelling and speech)
- Japanese: vowel devoicing/deletion in certain suffix environments
Consonant elision:
Consonants in difficult articulatory clusters are omitted:
- English: facts ? often [fæks] (middle /t/ deleted); next week ? [n?ks ‘wi?k]
- Final plosives in consonant clusters: old man ? [o?l mæn] (/d/ elided)
- supposed to → [spəʊzd tə] (/d/ elided); kept quiet → [kep kwaɪət]
Syllable elision (syncope):
Whole syllables deleted:
- comfortable ? [‘k?mft?b?l] (second syllable deleted)
- basically ? [‘be?sli] (middle syllable deleted)
- temperature → [ˈtɛmprətʃə] (middle syllables collapsed)
Schwa elision:
Unstressed schwa /?/ deletion is extremely common in English:
- history [‘h?stri] (schwa in second syllable)
- interesting → [ˈɪntrəstɪŋ] (second syllable schwa elided)
Elision in French
French has a highly regulated obligatory elision system — formal deletion of final /?/ (e schwa) and final vowel letters before initial vowels:
- le + ami ? l’ami
- ne + est ? n’est
This is grammaticalized as an orthographic rule, not just a speech phenomenon.
Elision vs. Assimilation
| Process | What happens |
|---|---|
| Elision | A sound is deleted (disappears) |
| Assimilation | A sound changes to be more like a neighbor |
Both often co-occur in connected speech: don’t you ? [do?nt?u] involves assimilation (/t/ + /j/ ? /t?/) AND vowel reduction.
Pedagogical Implications
Elision creates two primary challenges:
- Listening comprehension — spoken input contains elided forms that don’t match written or pronunciation-taught citation forms
- Prediction — learners must learn to predict that certain sounds will be omitted in connected speech based on phonological environment and speech register
Teaching connected speech phenomena including elision is a major component of advanced pronunciation instruction and academic/professional listening preparation (e.g., IELTS, TOEFL listening sections).
History
Elision has been described in grammars since antiquity (the Greek term ἔκθλιψις, ekthlipsis, was used for vowel elision in verse). Modern phonological treatment of elision began with 19th-century historical linguistics. Systematic studies of English connected speech elision were published by Gimson (1962), and by Brown (1990) in connected speech research.
Common Misconceptions
- “Elision is found only in casual/sloppy speech” — Elision occurs even in formal speech at natural rates; it varies in degree by register and rate but is present across all natural speech
- “Spelling tells you how words are pronounced” — English spelling famously masks elision: Wednesday [ˈwɛnzdeɪ], February [ˈfɛbjuəri], parliament [ˈpɑːləmənt]
Criticisms
- Connected speech pedagogy (teaching elision, assimilation, etc.) has been critiqued for potentially teaching learners to produce non-standard forms; some argue that receptive awareness is more important than production training for most learners
Social Media Sentiment
Connected speech including elision is a major topic in English listening comprehension content — “Why can’t I understand native speakers?” discussions almost always point to connected speech phenomena. Last updated: 2026-04
Practical Application
- Train receptive awareness of elision patterns in your TL through extensive authentic listening
- For English: focus on consonant cluster simplification, schwa elision, and final consonant loss before other consonants
- Use Sakubo to build vocabulary that anchors recognition of elided forms — knowing a word well means recognizing it even when sounds are missing
