perimetryn.

Brit.

/pᵻˈrɪmᵻtri/, U.S.

/pəˈrɪmətri/

Forms: 1500s perimetrie, 1800s– perimetry.

Origin: Formed within English, by derivation. Etymons: peri- prefix, -metry comb. form.

Etymology: < peri- prefix + -metry comb. form, after perimeter n.; compare geometry n., etc. Compare French périmétrie (1705 in sense ‘length of a perimeter’, 1963 in ophthalmology).

†1. A perimeter or circumference; the length of a perimeter. Obsolete.
