n. Usage Problem
A biceps, especially of the front upper arm.
Usage Note: The anatomical term for the muscle is biceps. The usual plural form of this word is identical to the singular: one biceps, two biceps. The word bicep is a back-formation created out of the mistaken impression that biceps is a regular English plural formed by adding -s to a singular noun. It is widely considered an error.


(ˈbaɪ sɛp)
a biceps muscle, esp. the one at the front of the upper arm.
