Morphology

assuming = assume (semi-transparent) = assume + ing

Formed from the verb 'assume' plus the adjectival/participial suffix '-ing'; the specific sense 'presumptuous' is a semantic shift from 'taking for granted' to 'taking liberties', so the relation is related but not fully transparent.

Etymology

The word assuming comes from the verb assume, which has parts ad- 'to' and sumere 'take'. So, to be assuming is like 'taking' a right or opinion for yourself without asking, which is why it means being too forward.
