It is the neuter of the adjective īnsectus (“indented, notched”),[2][1] the past participle of īnsecō1 (“to cut into”).[2][3] The word is a calque of Ancient Greek ἔντομον (éntomon, “insect”), Aristotle's term for these animals, which refers to their “notched” bodies;[4][1] Pliny the Elder made the loan-translation.[4][1]
Earliest recorded meaning
It is found in Pliny the Elder's Natural History, book 11, meaning an insect.[5][6][3]
Semantic evolution
Gaffiot enters it under the plural, īnsecta, “insects”.[6] English took it as insect about 1600; its first English use is in 1601, in Holland's translation of Pliny.[4]
