Morphology

at + random

The meaning 'without a specific pattern or purpose' is directly derivable from 'random' (occurring without method) combined with the preposition 'at' to form an adverbial phrase indicating manner. This is a straightforward compositional pattern common across languages, so a B1 learner who knows both words will readily infer the MWE meaning.

Etymology

At random makes you imagine someone scattering seeds by hand, so the seeds fall anywhere, not in neat rows. That's why it means 'without a plan or order'.
