The word "unfasten" is a combination of the prefix "un-" and the verb "fasten".
The prefix "un-" in English is derived from Old English "un-", which has a negating or reversing effect on the following word. In this case, "un-" negates the action of "fasten".
The verb "fasten" comes from Old English "fæstnian", which means "to make firm, to secure, to attach". It has Germanic roots and is related to similar words in other Germanic languages, such as Middle Dutch "vastnen" and Old High German "fastinōn".
Overall, the etymology of "unfasten" is a combination of the negating prefix "un-" and the ancient Germanic verb "fasten", which collectively mean "to undo or release something that is fastened or secured".
