How it's used

This character is almost exclusively used as a morpheme within the compound 瞳孔. While it refers to the pupil of the eye, you will rarely hear it standing alone in daily speech. It is considered a formal or medical term rather than a casual way to describe eyes.

Common mistake

Do not use this word to refer to the eye itself, which is 眼 or 眼珠. Using it in isolation will sound unnatural or overly poetic/literary to native speakers.
