Actually, I think it's debatable whether this word comes from a Latin masculinitas. Surely by the time this word came into being -ity was already productive on its own...
I only mention this because when I was looking up the etymology, I noticed masculinitas didn't appear to exist in Classical Latin—they appear to have used virilitas. If masculinitas came into being later it was likely recreated from another language's -ity/-ité/-idad formation, rather than being the source from which the others were derived. —Muke Tever 14:25, 24 Sep 2004 (UTC)
- masculinitas and feminitas do appear in British Medieval Latin (e.g. in Alfredus' translation Nicolai Damasceni de plantis libri duo), and are older than the (Modern) French term and the (Modern) English term. -184.108.40.206 13:22, 22 October 2017 (UTC)
