cuneus

Borrowed from Latin cuneus. Doublet of coign and coin.

cuneus (plural cunei)

1. (neuroanatomy) A portion of the occipital lobe of the human brain, involved in visual processing.
2. (entomology) A wedge-shaped section of the forewing of certain heteropteran bugs.
3. (architecture) One of a set of wedge-shaped divisions separated by stairways, found in the Ancient Roman theatre and in mediaeval architecture.

From Proto-Indo-European *h₂ḱū (“sting”) (which also gave culex (“mosquito”)), extended from *h₂eḱ- (“sharp”) (compare catus (“sharp”), acutus (“sharp”), cos (“whetstone”), Ancient Greek κῶνος (kônos, “cone”)).
