Morphology

look + up

The meaning 'to try to find information' is directly derivable from combining 'look' (to search) with the particle 'up', where 'up' adds a directional/completive sense common in English phrasal verbs indicating consulting or checking a source. Even though 'up' lacks a dictionary entry in the input, its typical particle meaning is familiar to B1 learners and the compositional pattern is cross-linguistically common, so learners who know both constituents will likely infer the MWE meaning.

Etymology

Look up comes from a simple image: when people needed facts they would open a book or lift their eyes to find them. People would look a word up in a dictionary, so it now means 'to try to find information'.
