Where does interlocked come from?
Interlocked is formed from the English prefix inter-, meaning “between” or “among,” and the verb lock, meaning to fasten securely. The prefix comes from Latin inter, while lock ultimately derives from Old English terminology for a fastening or bar. The compound interlock developed the sense of fastening or engaging together, and interlocked is its past tense and past participle form. Related English words include lock, unlock, and locker.
