Etymology

The word "inexplicable" traces back to Latin roots. The prefix in- negates, while ex- means "out." The root plic (from Latin plicare, "to fold") suggests "unfolding" or "explaining," combined with the suffix -able (capable of). Thus, "inexplicable" literally means "not capable of being unfolded (explained)." Over time, it evolved to describe something beyond logical clarification.
