How to pronounce milestone in American English
MAHYL·stohn
Start here
Americans pronounce milestone as MAHYL-stohn (/ˈmaɪlˌstoʊn/). The L in "milestone" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, and it's why Americans sound more relaxed than the textbook. It comes out as MAHYL·STOHN. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "Thank you for inviting us to celebrate this milestone with you".

Questions
Questions people ask about this.
How is "milestone" stressed in American English?
Stress falls on the first syllable — say "MAHYL" with a longer, fuller vowel and keep every other syllable short and quick. The respell "MAHYL-stohn" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Is the American pronunciation of "milestone" 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 "MAHYL-stohn" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
