Etymology
The word is a modern English compound formed by directly applying the common Latin-derived negating prefix 'non-' to the noun 'identity'. 'Identity' itself has a rich history, originating from the Latin idem, meaning "the same," which evolved into identitas in Late Latin to express the philosophical concept of sameness. The prefix 'non-', also from Latin, is a straightforward and productive means of forming negation, as seen in words like 'nonfiction' and 'nonsense'. Therefore, 'non-identity' logically constructs its meaning by combining these elements to denote the abstract state or proposition of not being the same, a term particularly useful in philosophical, logical, and mathematical discourse.
Analysis
Structure: non (not) + identity (sameness)
non: Latin origin, a prefix meaning "not," serving a negating function.
identity: From Latin identitas (sameness), via Late Latin idem (the same). The suffix -ity forms a noun indicating a state or condition.
