What does angulate mean?
To angulate is to make something angular — to replace smooth, rounded contours with distinct angles and sharp corners. The word functions chiefly as a transitive verb ('the designer angulated the building's facade'), but it can also be used intransitively to describe something becoming angular on its own, and it survives as an adjective meaning simply 'having angles'. Its natural habitat is technical language: anatomists speak of angulated bones and fractures, surgeons of angulated instruments, geologists of angulated rock fragments, and designers of deliberately angulated forms that reject softness for crisp geometry. Derived from the Latin 'angulus', meaning a corner or bend, it belongs to the same family as 'angular' and even 'ankle'. Precise and somewhat formal, 'angulate' rewards writers who need an exact term for the act of imposing angles on form.
To make or become angular; to give something angles or sharp corners in place of rounded edges.
"The architect angulated the roofline to echo the jagged mountain range behind it."
Used transitively far more often than intransitively; common in medical descriptions of bent or kinked structures.
Having angles or sharp corners; angular in shape.
"The beetle's angulate pronotum distinguishes it from its smoother-bodied relatives."
Frequent in entomology, botany, and other descriptive sciences, where precise shape terminology matters.
The same Latin root that gives 'angulate' its angles also gave you your ankles — the word 'ankle' descends from the Latin 'angulus', meaning corner or bend.

Etymology of angulate
Angulate comes from the Latin 'angulatus', the past participle of 'angulare', meaning to make angular, which itself derives from 'angulus', the Latin word for a corner or bend. It entered English in the early modern period, when Latin participial adjectives and verbs were widely adopted into scientific vocabulary. Its relatives include 'angular', 'angle', and 'triangle', all built on the same Latin root — and, more surprisingly, 'ankle', which traces back through Germanic borrowing to the same notion of a bend or corner.
