behind the eye socket

Etymology
Etymology Information

'postorbital' originates from Latin elements: the prefix 'post-' (Latin 'post') meaning 'after, behind', combined with 'orbital' ultimately from Late Latin 'orbita' meaning 'track, wheel' (later used for the eye socket area).

Historical Evolution

'postorbital' developed as a compound of Latin-derived 'post-' + Medieval/Modern Latin anatomical use 'postorbitalis' (meaning 'behind the orbit'), and entered English in anatomical and paleontological usage as 'postorbital'.

Meaning Changes

Initially formed to indicate position 'after/behind the orbit'; over time it became specialized in anatomy and paleontology to name either the region behind the eye socket or a specific bone there.
