noun kwəˈtəːn(ə)riˈkwɑdərˌnɛri

Geology

The Quaternary period or the system of deposits laid down during it.
〔地质〕第四纪（岩石）；第四系（岩石）

The Quaternary began about 1,640,000 years ago and is still current. Humans and other mammals evolved into their present forms, and were strongly affected by the ice ages of the Pleistocene

Origin

Late Middle English (as a noun denoting a set of four): from Latin quaternarius, from quaterni 'four at once', from quater 'four times', from quattuor 'four'.

Rhymes

fernery, ternary
