Morphology

perk + up

The meaning is directly compositional: 'perk' (become livelier) combined with the particle 'up' (indicating increase/improvement) yields ‘become more lively/cheerful’. This verb + particle pattern is a standard, predictable English construction, so a learner who knows both constituents can infer the MWE meaning.

Etymology

Perk up comes from the image of a dog or person suddenly lifting their ears or head; to perk is to lift or become more alert and up shows the movement. That small change shows more energy and interest, so 'perk up' means 'to become more lively or cheerful'.
