Morphology
lock + up
The meaning is directly built from 'lock' (to fasten or secure) plus the particle 'up', which here signals completion/intensification and confinement; a B1 learner who knows both words would readily infer that it means to secure or confine so someone/something cannot leave. This is a regular, compositional phrasal-verb pattern in English and is therefore transparent.
Etymology
Lock up comes from the clear picture of closing a gate or door and locking a person or animal inside so they cannot get out, with up showing they are fully held in. That's why it means 'to put someone in a place' they cannot leave, often to keep them safe or to stop them leaving.
