Meaning

Pure by later association, in the Catherine-derived route; original meaning uncertain.

The female Katherine short-name route is explicit; Welsh male-name, surname and other K-initial nickname routes are excluded. Catherine explicitly documents a Roman-era folk association with Greek katharos, pure, rather than a proven original derivation. Alternative ancient origins remain debated; no purity or personality is asserted for a bearer. Supporting evidence: https://en.wiktionary.org/w/index.php?title=Katherine&oldid=94540728 https://en.wiktionary.org/w/index.php?title=Catherine&oldid=93813067.

Origin

Multiple name routes: Welsh Cai-related male use, surnames, and Katherine or other K- female short forms.

The exact personal-name definitions explicitly distinguish these formations. A single rejoice, pure or keeper-of-keys meaning is not imposed across the unrelated routes.
