Origin & History of “life”

Prehistoric Germanic *līb- denoted ‘remain, be left’. from this was formed the noun *lībam, which in due course produced English life (the semantic connection between ‘remaining’ and life – and the closely related live – is thought to lie in the notion of being ‘left alive after a battle’). Of the noun’s Germanic relatives, Swedish and Danish liv still mean ‘life’, but German leib and Dutch liff have moved on semantically to ‘body’.

English alive is a derivative of life, not of the verb live.
