How to pronounce refill in American English
Americans pronounce refill as ree-FIHL (/riˈfɪl/). The L in "refill" 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, a small move that separates 'classroom' from 'native'. It comes out as ree·FIHL. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "I need to refill my prescription before it runs out".
