Talk:monstrum

Etymology
I disbelieve the claim that monstrum is a derivative of moneo (warn). If you look at the inflections of monere you will find no occurence of "str" which I would especially expect with the participles. How should this sequence get into the word? The verb monstro on the other hand looks very similar to monstrum in most of it's inflections. Now, the article on monstro also claims the same relationship with moneo. Does anyone have a reputable source to prove that moneo is the origin of monstro (inf. monstrare) and monstrum? --Zapyon (talk) 17:07, 27 August 2012 (UTC)
 * According to Duden, the verb monstrare is derived from the noun monstrum (which indeed suggests itself; it's a common form of derivation, while examples for the opposite direction are not known to me), and monstrum itself goes back to *monestrom, ultimately from monere. I'm not sure about the origin of the -s-, but -trum is a common instrumental suffix indeed. --Florian Blaschke (talk) 03:00, 5 August 2018 (UTC)

mens
Maybe the /s/ comes from the related word mens, gen. mentis, meaning "thought"? I also wonder if there is something to be seen in mensis "month" ( from which we get our word menstruation), which derives from the word for moon,  which we currently list as having an /s/ in PIE but which does not seem to be the familiar Indo-European nominative masculine /-s/. — Soap — 17:29, 8 May 2022 (UTC)
