detachable

The word "detachable" is built upon the verb "detach," which entered English in the 17th century from the French détacher. The French term itself was formed from the prefix dés- (expressing reversal, from Latin de-) and the verb attacher (to attach). The core concept of "attach" traces back to a Germanic root related to a stake or post, implying something fixed or fastened. By adding the Latin-derived suffix "-able," the adjective "detachable" was created, logically describing something that is capable of being unfastened or removed from its point of attachment. Thus, the word's literal construction—"capable of being unfastened off"—perfectly captures its modern meaning.
