A neologism for the “age of person” coined by Sami Paldanius and appearing in the VinQuettaParma Wiki (VQP) as a noun form ifant “age, (lit.) year-full”, so more literally “yearfullness”. Compare [N.] pathred “fullness”. Sami Paldanius gave it as íphathred, but I would render it as ifathred. I would contrast it with ioros which I would use for “age, oldness” of things as well as people.
