Forms

lautus (feminine lauta, neuter lautum, comparative lautior, superlative lautissimus); first/second-declension adjective, past participle of lavō[1] The participle also has the form lōtus, which the OLD finds used as an adjective perhaps only once, in Petronius.[1]

Etymology

It is the past participle of lavō (“to wash”), used as an adjective.[1][2][3] De Vaan traces ⟨lavō⟩ to Proto-Italic *lowa- (“to wash”) and Proto-Indo-European *(le-)louh3- (“to wash”), cognate with Umbrian vutu (“let him wash”), Ancient Greek λούω (loúō, “I wash”) and Old English lēaþor (“soap foam”).[4]

Earliest recorded meaning

The OLD's first example is in Ennius' Saturae, of a man “carefree, cheerful, washed”.[1]

Semantic evolution

Its first sense is “washed, clean”.[1][5] From this it came to mean “well turned out, respectable, fine”, as in Plautus' “she is charming and elegant — how sensible!”, and of conduct “splendid”, as in Cicero's letters: “nothing will be more splendid or glorious for you”.[1][2] Of a way of life, meals and furnishings it is “sumptuous, luxurious”: Seneca speaks of a region where the finest shelter is a hut.[1]

Church Latin glosses it “elegant, sumptuous, splendid, grand, washed”.[5]
