īnfēlīciter (comparative īnfēlīcius, superlative īnfēlīcissimē)[1]

Etymology

It is from Latin īnfēlīx (“unlucky”) + -ter, the adverb of the adjective.[2][1] The base goes back, through fēlīx, to Proto-Italic *fēl(w)ī- (“suckling”) and Proto-Indo-European *dʰeh₁-l(u)-i-.[3]

Earliest recorded meaning

It is first found in Terence,[4] in the Eunuchus, where a character meeting someone at the wrong moment calls it not just awkward but downright unlucky.[2]

Semantic evolution

Its first sense is “without good luck, unfortunately”;[2] from Livy on it also means “without success”, of an undertaking tried in vain.[2] It has a comparative īnfēlīcius and a superlative īnfēlīcissimē.[2][1]

Timeline

  • 190–159 BC – Terence uses it in the sense “unluckily”.[2][4]
