Why it sounds different

Why "compost" sounds like KAHM·POHST.

The "" at the end of "" is dropped before the consonant starting "" — the surrounding consonants flow directly together — common in flowing natural speech; in careful or formal speech, the sound is often kept. This is called the Silent T/D Across Words, what turns word-by-word reading into actual conversation. It comes out as KAHM·POHST.

Questions

Questions people ask about this.

How is "compost" stressed in American English?

Stress falls on the first syllable — say "KAHM" with a longer, fuller vowel and keep every other syllable short and quick. The respell "KAHM-pohst" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.

Is the American pronunciation of "compost" different from British English?

American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "KAHM-pohst" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
