all-or-nothing

The phrase 'all-or-nothing' is a modern English compound idiom, emerging in the late 19th to early 20th century, particularly in the context of psychology, gambling, and risk assessment. It is constructed from the fundamental, native English words 'all', 'or', and 'nothing', which themselves have deep Germanic roots tracing back to Proto-Indo-European. The logic of the phrase is purely syntactic and semantic, presenting an absolute dichotomy: one either receives everything ('all') or receives not a single thing ('nothing'), with the conjunction 'or' framing it as an exclusive choice. This stark binary formulation effectively captures the essence of high-stakes, zero-sum scenarios, evolving from a literal description to a widely used adjective for any approach or system that denies compromise.

This is a hyphenated compound idiom formed from three common English words. It is not productively formed from classical morphemes but is a fixed lexical unit.
