Origin and Evolution of unfasten

First Known Use: 1250 year
Language of Origin: Old English
Story behind the word: The word 'unfasten' originated from the combination of the prefix 'un-' meaning 'not' or 'opposite of' and the verb 'fasten' which comes from Old English 'fæstnian' meaning 'to make fast or firm'.
Evolution of the word: Over time, 'unfasten' has retained its original meaning of 'to release or undo something that was previously fastened'. However, its usage has expanded to include metaphorical meanings such as 'to loosen or relax a grip on something' or 'to free oneself from constraints'.
