Forms
obsolētus (feminine obsolēta, neuter obsolētum, comparative obsolētior, adverb obsolētē); first/second-declension participle[1]
Etymology
It is the participle from Latin obsolēscō (“to wear out, fall into disuse”), used as an adjective.[2][1] Wiktionary analyses that verb as obs- and olēscō (“to grow”),[1] while Etymonline takes it as ob- with an extended form of soleō (“to be accustomed”).[3]
Earliest recorded meaning
Köbler finds it first in Cicero,[4] who in the speeches on the agrarian law describes a man in rather shabby clothing, and in the Pro Quinctio calls a string of insults common and worn out.[2]
Semantic evolution
Of things it is worn out by age or use, and of people dressed in worn clothes, as Nepos and Livy use it;[2] Horace has a shabby, neglected house.[2] From there it means soiled or dingy, as Seneca's hand stained with blood and Suetonius' cloak of a dingy colour.[2] Of words and things it is hackneyed or commonplace: Cicero has a style a little too worn, and Nepos says that the honours of the Roman people had become lavish and cheap.[2] Seneca uses it of names fallen into oblivion.[2] Stelten gives “obsolete, worn out, cast off” for Church Latin.[5] English obsolete comes from it and dates from the 1570s.[3]
