Are “money” and “mind” cognates?

Question

Wiktionary gives me these pieces of information:

[money] [1]

From Middle English moneie, moneye, from Old French moneie (“money”), from Latin monēta, from the name of the temple of Juno Moneta in Rome, where a mint was.

Displaced native Middle English schat (“money, treasure”) (from Old English sceatt (“money, treasure, coin”)), Middle English feoh (“money, property”) (from Old English feoh (“money, property, cattle”)).

[mint-2] [3]

From Middle English mynt, münet (“money, coin”), from Old English mynet (“coin, money”), from Proto-Germanic *munitan, *munitō (“coin”), from Latin monēta (“place for making coins, coined money”), from the temple of Juno Moneta (named for Monēta mother of the Muses), where coins were made; akin to Dutch munt (“currency, coin, mint”), German Münze (“coin, coinage, mint”), Danish mønt (“coin”), and to Russian монета (“coin”).

[mind] [4]

Cognate with Gothic 𐌼𐌿𐌽𐌳𐍃 (munds, “memory, mind”), Old English myntan (“to mean, intend, purpose, determine, resolve”), Latin mens,mentis (“mind, reason”), Albanian mënd (“mind, reason”). More at mint.

------------------------------------------------------------------

There are two etymologies, mint-2 and mint-1 provided for mint, referring respectively to two meanings: "a coin/place making coins" and "intent to do".

(Q1)So are mint-1 (intent to do) and mint-2 (a coin) cognates or not?

If they are not cognates, given that money is cognate with mint-2 (a coin) while mind is cognate with mint-1,

(Q2)can we draw the conclusion that money and mind are not cognates?

Answer 1

Yes, they're all related.

The Latin name Monēta comes from the verb moneō, monēre, monuī, monitus, 'to warn'. "Juno the Warner" was a cognomen of the goddess Juno; there's a story about geese in the link. The fact that the Roman mint was located (and named) at the temple of Juno Moneta is a coincidence. That's where a lot of names come from.

But, to return to the question, the etymology of moneō is very interesting. It turns out to be an O-grade ablaut variant of the PIE *men- 'mind' root, same as the other ones. But it's a Causative. Warn is a causative in PIE because it meant 'cause to think (of)'. And they had a way to indicate this.

PIE was highly inflected, like Sanskrit, and it had a causative aspect, which was a suffix -i- or -iy- before the person/tense inflection. The PIE would have been something like mon-iy-, and by Latin that had become mon-ē-.

This "yodated causative" -iy- suffix came down into English too, surviving as a fossil palatalization in words like drench, which comes from older drink-y-an and meant 'cause to drink'. Thus, at some point in English history, you could lead a horse to water, but you couldn't drench him.

Many English verbs that end in [tʃ] or [dʒ] can be paired off with an non-causative verb like drink/drench. For instance, milk/milch, dike/ditch, make/match, blank/blanch, wring/wrench, and the like (vowel changes happen often, but consonants tend to linger).
