the word 'unsurprisingly' is built upon the core verb 'surprise,' which entered english from old french 'surprendre,' meaning "to overtake" or "seize." this, in turn, derives from latin 'superprehendere,' combining 'super-' (over) and 'prehendere' (to grasp). the negative prefix 'un-' of old english origin is added to the adjective 'surprising' (itself formed with the '-ing' participial suffix) to create the opposite quality. finally, the old english adverbial suffix '-ly' is appended, completing the logical construction of an adverb meaning "in a manner that is not causing wonder or astonishment," hence, as expected.
