Morphology

split + one's + side

The components 'split' and 'sides' create a vivid bodily image implying an extreme physical reaction, so there is a clear metaphorical link to intense laughter; however the specific sense 'to laugh very hard' is not directly predictable from the literal meanings alone for a B1 learner. Similar metaphors exist in other languages (e.g. Spanish 'partirse de risa'), which can help, but the idiomatic mapping remains partly unpredictable without prior exposure.

Etymology

The idiom split one's sides comes from an old image of laughing so much that your body feels like it will split at the sides. One popular story says people long ago talked about laughter 'splitting' the ribs, so today the phrase means 'laugh very hard'.
