Etymology
The OLD derives it from Latin senex (“old man”) + -ium;[2][3] Lewis & Short connect it with seneō (“to be old”).[2][3] De Vaan lists it among the derivatives of senex, and notes it may be formed from an o-stem noun, like senīlis.[4] He traces the family to Proto-Italic *seno- (“old; old man”) and Proto-Indo-European *sen-(o-) (“old”), comparing Old Irish sen (“old”), Sanskrit सन (sána-, “old”), Ancient Greek ἕνος (hénos, “old, of last year”) and Lithuanian sẽnas (“old”).[4]
Earliest recorded meaning
De Vaan and Köbler date it from Plautus.[4][5] The OLD's earliest quotation is from Ennius, of a brave horse that rests, worn out by old age.[2]
Semantic evolution
It is the condition of old age, usually with the idea of decay: Cicero writes of a work free from all disease and decay.[3] It can be the period of old age itself, as in Lucan, and in Statius the long course of an age.[2] Early on it also meant gloom and melancholy, or a cause of grief: Pacuvius lists it with fear, want and sorrow.[2] Wiktionary gives a rare use for an old man.[1] Church Latin glosses it senility.[6]
