Common Mispronunciations of Serum

Not suh-RUHM

The front syllable takes the beat and the ending is a light ruhm. A loud second half makes it sound like the Latin plural sera.

Not SEE-ruhm

The first vowel is short in both main accents, closer to the i of sit in America and the e of set in Britain, never the ee of see.

Tip: Americans usually say SEER-uhm and the British SE-ruhm, which is the same split you hear in the word era.
