Morphology

basic + assumption

The phrase combines 'basic' (fundamental, core) with 'assumption' (a supposition accepted without proof), so its meaning 'a fundamental supposition that underlies an argument or theory' is directly derivable from the constituents. This compositional structure is common across languages and follows normal adjective+noun semantics, so a B1 learner who knows the two words would readily understand it.

Etymology

Basic assumption gives the image of a building: basic is the low base and assumption is a belief placed on it. That's why it means 'a fundamental idea taken for granted'.
