What does geniculate mean?
Geniculate is a formal adjective describing something bent at a sharp angle or articulated at a joint. It is especially associated with anatomy, where it appears in terms such as the geniculate ganglion and geniculate body, referring respectively to a bend in the facial nerve and a visual relay structure in the brain. The adjective can also describe a sharply flexed or angular body form. As a rare verb, geniculate means to form an angle or provide something with a joint. The word derives from Latin geniculatus, meaning "of the knee," and ultimately from geniculum, "little knee." In ordinary speech it sounds technical rather than everyday, but it is useful when precision matters: it distinguishes a particular angled or jointed structure from one that is merely curved. Its historical meaning preserves an image of a knee, making it one of the more memorable anatomical words borrowed directly from Latin.
Bent or jointed at a sharp angle; relating to a knee-like bend or to a geniculate ganglion or body.
"The surgeon identified the geniculate ganglion on the patient's MRI."
Common chiefly in anatomy and other technical descriptions of angled or jointed structures.
To form an angle or joint; to bend or articulate.
"The articulated arm geniculates at the elbow."

Geniculate comes from Latin for "little knee," preserving the image of a sharp bend in its sound and meaning alike.

Where does geniculate come from?
Geniculate entered English in the early 17th century from Latin geniculatus, "of the knee; jointed; bent at an angle." The Latin adjective was formed from geniculum, a diminutive of genu meaning "knee," literally "little knee." The same Latin root underlies cognates such as English genu and genuflect, while geniculum supplied the word's immediate source.
How geniculate is actually used
Geniculate is formal and specialized. As a plain descriptive adjective it is uncommon, while as a verb it is rare and may sound technical or archaic.
