Morphology

on + the + spur + of + the + moment

The meaning 'suddenly, without planning' can be inferred from combining 'spur' (an impetus or stimulus) with 'moment' (a very short time) — i.e. acting on an impulse in the moment — so a learner who knows the constituent senses can reach the intended meaning. However, 'spur' is used figuratively here and the full fixed prepositional phrase is conventionalized, so the relation is not completely literal or fully predictable for all learners.

Etymology

The phrase on the spur of the moment may come from horse riding. A rider touches a horse with a metal spur to make it move at once, so the phrase means 'suddenly, without planning'.
