How to pronounce Same-Consonant Linking C–C in American English
Consonant is held slightly longer and released once (not said twice).
When a word ends with a consonant and the next word starts with the same consonant, Americans don't say it twice — they hold it once, slightly longer, and release it once. Black cat comes out as blac-cat with one held /k/; some more as som-more with one held /m/; bus stop as bus-stop. Releasing both consonants puts an awkward pause between the words. Holding once lets the phrase land as a single rhythmic unit.
Watch it happen in real phrases.
Three example phrases showing exactly when this rule fires.
black cat
The /k/ at the end of black and the /k/ at the start of cat are the same articulation — back of tongue against soft palate, airflow blocked. Instead of releasing the first /k/ and articulating a new one, the tongue just holds the closure a beat longer and releases once. Two /k/s come out as one held /k/. Same closure holds for every stop at a word boundary — good day, right turn, big game.
some more
Same mechanic with a nasal. The /m/ at the end of some shares its lip-closure with the /m/ at the start of more, so the lips stay shut a beat longer and the nasal vibration carries continuously into the next word — som-more. What you hear is just length, not two separate /m/s. Any nasal at a word boundary does the same — in need, thin noodle, run north.
bus stop
Fricatives merge the same way. The /s/ at the end of bus blends with the /s/ at the start of stop into a single longer hiss — bus-stop. Same with this Sunday, nice service, cross section — anywhere /s/ meets /s/ at a word boundary.

Real phrases where this rule fires across the word boundary.
In real American conversation.
Listen for any phrase where one word's final consonant matches the next word's first. Bus stop, good day, gas station, black cat, some more, this Sunday, stop pushing — the consonant lands once and gets held. Conversations, podcasts, sitcom dialogue: unless someone is enunciating very deliberately, the doubled consonant merges into a single longer hold.
Five sentences where the consonant holds instead of starting twice.
Each one has a word boundary where the same consonant ends one word and starts the next. Tap to hear the single held release — no gap, no restart.
