Morphology

in + use

The meaning 'being used or occupied' is directly derivable from combining the preposition 'in' (indicating a state or location) with the noun 'use' (the action or function), so the phrase literally describes something that is within use. This compositional preposition + noun pattern is common cross-linguistically and follows standard English patterns, so a B1 learner who knows both words will readily understand 'in use'.

Etymology

In use comes from the simple picture of something being in use: imagine a chair with someone sitting on it, so the chair is not free. So in use means 'being used' or 'occupied' now.
