Surface Forms

in operation positive

Morphology

in + operation

The meaning 'functioning or actively working' is directly and transparently derived from 'in' (indicating a state/location) + 'operation' (a process of functioning); a B1 learner who knows both words can infer the phrase means something is currently working. This preposition + noun state construction is common in English and in many other languages, so the sense is predictable and easily comprehensible.

Etymology

In operation comes from the sight of machines or systems working: when a machine is switched on it is literally in operation, doing its work. So calling something in operation means it is 'functioning' or 'actively working' now.
