How to pronounce cells in American English
SEHLZ
Start here
Americans pronounce cells as SEHLZ (/sɛlz/). The L in "cells" 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 SEHLZ. You'll hear it in sentences like "The radiation therapy aims to destroy cancer cells" or "He observed the cells under a high-powered microscope" — more examples below.

Is the American pronunciation of "cells" 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 "SEHLZ" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
