Morphology

go + off + half-cocked

The verb phrase 'go off' can mean to start acting or speaking, and 'half-cocked' (from the firearm metaphor of being only partially cocked) conveys being insufficiently prepared; together they point toward acting rashly. However, the firearm-derived sense of 'half-cocked' and the idiomatic combination are culturally specific and not fully predictable for a B1 learner who only knows the literal words, so the expression is only partially transparent.

Etymology

Go off half-cocked may come from old guns. If a gun was half-cocked the hammer was not fully set and could go off, so the phrase now means 'to act before you're ready'.
