Etymology

The word "irresistible" traces back to Latin roots. The prefix "ir-" (variant of "in-") negates the following root, "resist," derived from Latin "resistere" ("to withstand"). The suffix "-ible" (from Latin "-ibilis") indicates capability. Thus, the literal meaning is "not capable of being withstood." Over time, it evolved to describe anything too compelling or powerful to oppose, whether emotions, desires, or physical forces.
