rictusn.

Brit.

/ˈrɪktəs/, U.S.

/ˈrɪktəs/

Inflections: Plural ricti, rictuses.

Origin: A borrowing from Latin. Etymon: Latin rictus.

Etymology: < classical Latin rictus open mouth or jaws < rict- , past participial stem of ringī to open the mouth wide, show the teeth (perhaps < the same Indo-European base as Old Church Slavonic rǫgŭ , Old Russian rug′′ mockery, Russian rugat′ to berate) + -tus , suffix forming verbal nouns. In sense 1b after scientific Latin rictus ( Linnaeus Philosophia Botanica (ed. alt., 1763) 227). Compare earlier ricture n.The plural of classical Latin rictus (u-stem) is rictūs; the English plural form ricti is by analogy with the plurals of (much commoner) Latin o-stem nouns in -us.

a. Chiefly Zoology. The opening or gape of the mouth. Also: the edge of the opening of the mouth; spec. the angle of the mouth.
