Origin of -ant⁴

< Latin -ant-, present participle stem of verbs in -āre; in many words < French -ant < Latin -ant- or -ent- ( see -ent); akin to Middle English, Old English -and-, -end-, present participle suffix

Explanation

An ant is an insect that lives and works in a large colony of ants. Most ants don't have wings, and some of them have stingers. Ants are related to both bees and wasps, and like them are social insects. Ant colonies can include anywhere from a few dozen to millions of ants, divided into jobs or castes. There isn't a continent in the world that doesn't have ants living there. The Middle English word for ant was ampte, from the Old English æmette and a Germanic root.
