Gemination
Gemination is the lengthening of a consonant, typically occurring at a word or morpheme boundary where the same consonant ends one word and begins the next. The result is not two separate articulations but a single prolonged closure or friction.
Examples
| Sequence | Transcription | What happens |
|---|---|---|
| bus stop | /bʌs stɒp/ | Prolonged [sː] — one long friction, not two separate /s/ sounds |
| black cat | /blæk kæt/ | Extended velar closure [kː] — one long hold, single release |
| bad day | /bæd deɪ/ | Prolonged alveolar closure [dː] |
| some more | /sʌm mɔː/ | Extended bilabial closure [mː] |
| night time | /naɪt taɪm/ | Extended alveolar closure [tː] |
| pen knife | /pen naɪf/ | Extended nasal [nː] |
Phonetic Reality
With geminate Plosives, the articulators make contact and hold the closure for approximately twice the duration of a singleton, then release once. There is no separate release-and-re-closure. For fricatives, the friction continues without interruption. For nasals, nasal airflow is sustained through the extended closure.
English vs Other Languages
In English, gemination is not phonemic — it does not distinguish word meanings. It occurs only across morpheme or word boundaries (so-called "fake" or "concatenated" geminates). This contrasts with languages where gemination is contrastive:
- Italian: fato (fate) vs fatto (fact) — gemination changes meaning
- Japanese: kite (come) vs kitte (stamp)
- Arabic: darasa (he studied) vs darrasa (he taught)
In Casual Speech
In rapid, casual speech, gemination may be reduced — some more pronounced with a single short [m]. This degemination is a natural feature of fast speech and does not impede communication.
Teaching Relevance
Gemination is a relatively minor feature for pronunciation teaching, but awareness of it helps learners:
- Understand why word boundaries can be hard to perceive in fluent speech
- Produce natural-sounding Connected Speech at word boundaries
- Avoid inserting a vowel between identical consonants (bus-uh-stop)
