Morphology

break + a + promise

The sense 'to fail to do what you have promised' is directly and predictably derived from combining 'break' (to violate or stop/interrupt) with 'promise' (an assurance). This construction mirrors common cross-linguistic usage (e.g., Spanish 'romper una promesa', French 'rompre une promesse') and follows regular English collocation patterns, so a B1 learner who knows the parts will understand it.

Etymology

Break a promise comes from a simple image: a promise is like a small thing you can break, such as a wooden stick or a pinky-swear. So when you break a promise you lose the agreement and people's trust, meaning 'to fail to do what you promised'.
