Morphology

listen + in

The verb 'listen' plus the particle 'in' readily suggests listening into something, so a learner who knows both words can infer that it means to attend to a conversation or broadcast. However, the specific pragmatic sense of doing so quietly or without permission is an extended/idiomatic use of the particle 'in' and is not fully predictable from the literal meanings, so the expression is only partly transparent.

Etymology

The phrasal verb listen in comes from the simple image of someone putting their ear close to a door or group so their listen is in the conversation and they try not to be seen. That's why it means 'to listen secretly' or 'without permission'.
