Forms
senīlis (neuter senīle, adverb senīliter); third-declension two-termination adjective[1]
Etymology
It is from Latin senex (“old, old man”) + -īlis.[2][3][1] De Vaan notes that it can also come from an older o-stem, as servīlis (“slavish”) and puerīlis (“childish”), and traces senex to Proto-Italic *seno- (“old”) and Proto-Indo-European *sen-(o-) (“old”).[4] Cognate with Old Irish sen (“old”), Ancient Greek ἕνος (hénos, “of last year”) and Lithuanian sẽnas (“old”).[4]
Earliest recorded meaning
The OLD's first example is in Naevius' comedy, of an old man handling a worn-out fire-shovel.[2] Köbler dates it from Cicero.[5]
Semantic evolution
It means of or proper to an old man, as Cicero's Tages, a boy in appearance but with an old man's wisdom, and his contrast of something old in a young man;[3][2] Horace sets the parts of old men against those of men in their prime.[3][2] Seneca applies it to a particular old man, as Nestor's Pylos.[2] Of persons and their bodies it means old or aged, as Ovid's old man's cheeks wet with tears and his trembling hands, and of conditions inveterate.[2] Church Latin glosses it old, aged, senile.[6] English senile (1660s) came through French.[7]
