Morphology

unexecutable = executable (transparent) = un + execute + able

The adjective is formed by adding the negating prefix 'un-' to 'executable', a standard and semantically regular negation.

Etymology

The word unexecutable starts with un- meaning 'not', then execute meaning 'to carry out' or 'to run', and the ending -able meaning 'can be done'. So, unexecutable simply means something that 'cannot be carried out' or 'cannot be run', often used for a computer file or a plan that will not work.
