Common mistakes

Stressing the wrong syllable.

Stress falls on the third syllable, not the others. Stretch NOON — keep everything else short and quick.

Pronouncing the "R" too clearly.

Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.

Questions

Questions people ask about this.

How is "afternoon" stressed in American English?
Stress falls on the third syllable — say "NOON" with a longer, fuller vowel and keep every other syllable short and quick. The respell "af-ter-NOON" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
How do I pronounce the R in "afternoon"?
Americans use a relaxed retroflex R: the tongue curls back rather than rolling, and the R is one continuous sound with the vowel before it — not two separate sounds. Don't try to pronounce a separate vowel followed by a separate R. Treat them as a single shape.
Is the American pronunciation of "afternoon" 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 "af-ter-NOON" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
