Pronunciation
Forms
senex m or f (genitive senis); third declension[1] Plautus has an old nominative plural senicēs, and an old genitive senicis is reported.[2][3] The comparative is senior.[2]
Etymology
It is inherited from Proto-Italic *sen-ek- (“old man”), inherited from Proto-Indo-European *sen-(o-) (“old”).[4][1] De Vaan suggests that an older thematic *seno-, as in Celtic, became an i-stem in Latin under the influence of iuvenis.[4] Cognate with Old Irish sen (“old”), Welsh hen (“old”), Sanskrit सन (sána-, “old”), Ancient Greek ἕνος (hénos, “of last year”), Lithuanian sẽnas (“old”) and Gothic 𐍃𐌹𐌽𐌴𐌹𐌲𐍃 (sineigs, “old”).[4][2]
Earliest recorded meaning
Naevius speaks of an old man who, trusting in the gods, prayed to Neptune.[2][4] Köbler dates Naevius c. 235–200 BC.[5]
Semantic evolution
It was an old man and, as an adjective, old or aged, as Cato's advice to sell an old slave.[2] Wiktionary places it above iuvenis in age.[1] Its derivatives senātus “council of elders” and senior “older” became words of rank.[4][6] Döderlein contrasts it with vetus and with iuvenis.[7]
Medieval writers also used it of Satan.[8] It survives as Romanian sânec, and was borrowed as Italian sene.[1] English senate and senior come from its derivatives.[6]
