Circumflex

Curved like a bow.

In anatomy, circumflex describes a structure that bends around like a bow.

For example, the circumflex branch of the left coronary artery.

In linguistics, a circumflex is a caret-shaped mark (^) used over a vowel to indicate the pronunciation, length or the omission of a letter formerly pronounced.

In French, it is called 'un petit chapeau' (a little hat).

From the Latin circumflexus, bent around, circumflex, past participle of circumflectere, to bend around : circum- + flectere, to bend.
