Morphology

sit + up

The meaning 'to move from a lying or leaning position to an upright sitting position' is directly and transparently composed from 'sit' (to be seated) and 'up' (toward a higher position). This verb+particle motion/resultative pattern is common in English and cross‑linguistically, so a B1 learner who knows the constituents will readily infer the MWE meaning.

Etymology

The verb sit up shows the physical move from lying down to a sitting position, like a baby learning to sit up or a person who wakes and sits up in bed. So sit up means 'move to a sitting position'.
