🌳Etymology

Prefixper--
Rootpendic-
Suffix--ular

Origin

From Latin perpendicularis, derived from the verb pendere meaning 'to hang' or 'to suspend'. The prefix per- (thoroughly) combined with pendere evokes the image of something hanging completely vertically under the force of gravity, establishing the geometric meaning of a line at right angles to another.

Breakdown

per- (thoroughly, completely) + pendere (to hang, suspend) + -icular (adjective suffix, resembling or relating to). The compound literally describes something that hangs straight down or is oriented at a right angle.
