Morphology

post-haste = post + haste (semi-transparent) = post + haste

The components 'post' and 'haste' are recognisable, but the idiomatic adverbial meaning 'with all possible speed' is conventionalized and the role of 'post' (historically 'postal' speed) is not obvious to all learners.

Etymology

Post-haste comes from post ('mail' or the person who carried letters) and haste ('quickness' or 'hurry'), so it once meant doing something at the speed of the post. So today post-haste still means to do something 'as quickly as possible'.
