Morphology

unfastener = unfasten (transparent) = un + fasten + er

The agent noun is formed by adding the productive suffix '-er' to the verb 'unfasten', which itself is transparently 'un-' + 'fasten'.

Etymology

The word unfastener comes from the parts un- ('not' or 'reverse'), fasten (from fast, meaning 'firm' or 'held tight') and -er for a person, so an unfastener is someone who undoes what is held tight, like opening a buckle, knot, or package.
