Morphology

unforeseen = foreseen (transparent) = un + foresee + en

The adjective is formed by adding negative prefix 'un-' to the participle 'foreseen'; the meaning 'not predicted' is directly derivable.

Etymology

Unforeseen is made of un- meaning 'not' and fore- meaning 'before', so it literally says 'not seen before'. Think of an unforeseen storm you did not see coming; that's why the word means 'not expected'.
