Morphology

work + up

The sense of emotions building or intensifying is partly derivable from combining 'work' (to develop or produce gradually) with 'up' (to increase/intensify), so a learner could infer it involves feelings growing. However, the specific idiomatic use meaning 'become agitated/upset' is a conventionalized phrasal-verb sense and not fully predictable from the parts, so it would likely require prior exposure for a B1 learner.

Etymology

Work up shows a picture of work and up: someone shaping rough notes and lifting them into a finished plan, so it means 'to develop or produce something'.
