Common pronunciation mistakes in American English.
The textbook way isn't wrong — it's just not how anyone actually says it.
01
Releasing the final consonant with a puff of air.
In "factor", the "t" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
factor→FAK·ter
02
Stressing the wrong syllable.
Stress falls on the first syllable, not the others. Stretch FAK — keep everything else short and quick.
fak·TER→FAK·ter
03
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.
… (no R)→… r (curl the tongue)
Questions
Questions people ask about this.
How is "factor" stressed in American English?
Stress falls on the first syllable — say "FAK" with a longer, fuller vowel and keep every other syllable short and quick. The respell "FAK-ter" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
How do I pronounce the R in "factor"?
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 "factor" 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 "FAK-ter" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
