Forms
impexus (feminine impexa, neuter impexum); first/second-declension adjective[1] It is also spelled inpexus.[2][3]
Etymology
It is from Latin in- (“not”) + pexus (“combed”),[1][4] the participle of pectō (“to comb”).[2] That verb goes back to Proto-Italic *petke/o- (“to comb”), which de Vaan, following Pinault, derives from a reduplicated Proto-Indo-European *pe-pḱ-.[5] Cognate with Ancient Greek πέκω (pékō, “to comb, shear”) and Lithuanian pèšti (“to pluck”).[5]
Earliest recorded meaning
Pacuvius is the first to use it.[5][6][7]
Semantic evolution
It is mostly poetic and post-Augustan.[3] Virgil has icicles stiffening in uncombed beards, stīriaque impexīs indūruit horrida barbīs,[3] and the hide of a lion shaggy with fearsome bristles;[2] Horace a head foul with unkempt scurf;[3] and Tibullus Tisiphone, impexa, with wild snakes for hair.[3] Tacitus uses it figuratively of the dull, unadorned style of the ancients.[8][7]
Medieval writers used it of uncombed hair, as Orderic Vitalis does,[9] of raw wool and of things shaggy or spiky,[10] and as a neuter noun for a rough cloth.[10]
