(unfastener)
things or people that undo fastenings
Etymology
'unfastener' originates from English, specifically formed from the prefix 'un-' + the verb 'fasten' + the agentive suffix '-er', where 'un-' meant 'not' or 'reverse', 'fasten' came from Old English 'fæstnian' meaning 'to make firm', and '-er' denotes 'one who'.
'unfastener' developed as an agent noun from Middle English formations combining 'un-' and 'fasten' (from Old English 'fæstnian'), adding '-er' to indicate an instrument or person; this produced the modern English 'unfastener'.
Initially it meant 'one or something that undoes what is fastened', and this core meaning has remained largely the same in modern usage.
