Etymology

The word lost originates from Old English losian ("to perish, be lost"), derived from Proto-Germanic lausaz ("loose, free"). The past tense form lost emerged in Middle English, retaining the core idea of "separation" or "absence." The modern sense evolved to emphasize both physical displacement ("unable to find") and abstract loss (e.g., time, opportunities). The suffix -t marks its past tense form, aligning with Germanic verb conjugation patterns.
