Morphology

know + about

The meaning 'to have information concerning' is directly and compositionally derived from 'know' (be aware of facts) + 'about' (concerning a topic); a learner who knows both words will naturally interpret this combination as knowledge regarding a subject. This construction follows a common and predictable grammar pattern across languages, so an average B1 learner should understand it without prior exposure.

Etymology

Know about comes from a simple picture: know means to have facts and about means around a subject, so imagine facts pinned around a picture so you can see what is known. That's why it means 'to have information about' someone or something.
