Consonant Gemination When identical consonants meet at word boundaries

What is it?

When a word ends with the same consonant that the next word begins with, speakers don't pronounce the sound twice. Instead, the consonants merge — but how they merge depends on the type of consonant.

some money /sʌm mʌni/ [sʌ mʌni]

This is why "some money" sounds like "suh money" — the two /m/ sounds become one longer /m/.

Three types of consonants

1. Continuous consonants — Lengthening

Fricatives (/f, v, θ, ð, s, z, ʃ, ʒ/), nasals (/m, n, ŋ/), and liquids (/l, r/) can be held continuously. When they meet, the sound is lengthened — pronounced once, but for a longer time.

bus stop/bʌs stɑp/[bʌːstɑp]
phone number/foʊn nʌmbɚ/[foʊːnʌmbɚ]
more rice/mɔr raɪs/[mɔːraɪs]

2. Stops — Hold and release

Stops (/p, b, t, d, k, g/) cannot be held continuously because they completely block airflow. When they meet, the first stop is held, then released into the second. This creates a brief pause.

3. Affricates — Pronounced twice

Affricates (/ʧ, ʤ/) are pronounced twice without merging.
