antique

antique: [16] Originally, in Latin, antique was an adjectivized version of the adverb and preposition ‘before’: to ante ‘before’ was added the adjective suffix -īcus, to produce the adjective antīquus (somewhat later an exactly parallel formation, using the suffix -ānus rather than -īcus, produced the adjective which became English ancient).

English acquired the word either via French antique or directly from Latin. To begin with, and until relatively recently, it meant simply ‘ancient’, or specifically ‘of the ancient world’; it was only towards the end of the 18th century that the modern sense ‘made long ago and therefore collectable’ began to become established. In Italian, antico (from Latin antīquus) was often applied to grotesque carvings found in ancient remains.

It was borrowed into English in the 16th century as an adjective, antic, meaning ‘bizarre’, but also as a noun, usually used in the plural, in the sense ‘absurd behaviour’.
