Describing something shaped like or relating to a bed or couch, or in anatomy, relating to the clinoid processes of the sphenoid bone.
From Greek klinē (bed) plus -oid (resembling), literally meaning 'bed-like'; anatomically referring to small projections in the skull shaped like bedposts.
The clinoid processes in your skull literally got their name because they look like the corner posts (clinoi) of an ancient Greek bed—ancient anatomists had poetic ways of describing body parts!
