check up on infinitive

Morphology

check + up + on

The verb 'check' (inspect) combined with particle 'up' and preposition 'on' yields a meaning directly related to inspecting or looking into the state of something or someone; the components contribute predictable roles (inspect + thoroughness/completion + target). This phrasal construction follows common English verb + particle + preposition patterns and has clear cross-linguistic parallels, so a B1 learner who knows the parts will generally be able to infer the meaning.

Etymology

Check up on comes from the image of a doctor doing a regular check up on a patient, looking closely to see how they are. So, it means 'to examine' or 'to make sure something is okay'.
