The word "incompatible" originates from Latin in- (meaning "not") + compatibilis ("able to coexist"). The root compatibilis itself derives from com- ("together") + pati ("to suffer, endure"), reflecting the idea of enduring or functioning together. Over time, "incompatible" evolved to describe things that cannot coexist or function together, whether in relationships, chemistry, or technology.
