live-and-let-live

The phrase "live and let live" is a proverb of Germanic origin, crystallizing a pragmatic philosophy of mutual tolerance. Its structure is a direct imperative clause from Middle English, built from the core Germanic verbs libjaną (to live, be alive) and lētaną (to allow, to let). The logic is explicitly literal: the instruction "live" is paired with "let live," creating a reciprocal compact. This concise formulation evolved from broader proverbial wisdom, gaining particular prominence in the 17th century to describe a principle of non-interference, whether in personal conduct, commerce, or, later, warfare, where it denoted an informal truce between opposing forces.

This is a fixed idiomatic phrase functioning as a compound adjective or noun. It is not productively segmented into smaller morphemes for analysis in the same way as a single lexeme. Its meaning is derived from the imperative construction of the verbs 'live' and 'let'.
