Morphology

unpredictably = unpredictable (transparent) = un + predict + able + ly

Formed by adding the productive adverbial suffix '-ly' to the adjective 'unpredictable', so the final step is a direct and regular derivation.

Etymology

Unpredictably breaks into parts that show its meaning: un- 'not', pre- 'before' plus dict 'say', and -ly 'in a way'. So, something that happens unpredictably is something you could not 'say before', which is why it is unexpected or hard to guess.
