Morphology

night + owl

The phrase maps metaphorically from a nocturnal animal (owl) to a person active at night, so a learner who knows that owls are active at night can readily infer the meaning. However the connection relies on world knowledge about owl behaviour (and is not literally compositional), making the sense partly but not fully predictable for all B1 learners. Cross-linguistic parallels (e.g., German Nachteule) increase its recognizability but do not make it fully transparent.

Etymology

The noun night owl comes from the bird owl, which is awake in the night, so people used this image to call someone who 'stays up late' a night owl.
