The etymology of "Adam" has anything to do with "Adom," hence "dominion"?

My Sunday school teacher once talked about the origin of the word "Adam" being associated with "Adom", which takes on the meaning of "dominion". Biblically speaking, I think this unconventional explanation could be quite appealing to Christians alike, but I'm really doubtful of its validity.

As Merriam-Webster Dictionary says, Adam originated from "Middle English, from Late Latin, from Greek, from Hebrew Ādhām", meaning "man" (New Oxford American Dictionry, 2nd ed).So this is the first time I heard it explained otherwise. Any evidence of that?

The Oxford English Dictionary supports the etymology given by M-W. The core meaning of Adam is ‘mankind’. There may be further connections with words from various languages meaning ‘earth, ground’ and ‘ruddy’. I’m not sure if it has any relevance, but Edom is another name for Esau.

There seems to be no recent etymological connection with words like dominion, which derives from Latin dominium, meaning ‘property’, and, ultimately, from dominus, meaning ‘lord’. There may just be the possibility that in Indo-European dominus had something in common with the word that produced Adam, but, unless someone knows better, that is speculation.

The connection is spurious for the simple reason that Adam has its roots in Hebrew, an Afro-Asiatic Semitic language; whereas Dominion has latin roots and thus is ultimately an Indo-European word.

The etymology of Adam comes from the classical Hebrew word for earth, man, soil (Genesis 2 speaks of God forming Adam out of "the dust of the ground".) This word is related to adamah which means "ground" and dam which is the Hebrew word for blood.

Dominion comes from the latin word dominus (lord/master) which literally means "master of the house" (domus = home, hence the english words domestic and domicile.) Another english word which is derived from this root is timber — material used to build the home.

Both the Semitic origins of Adam and the Indo-European root dom are likely at least 5000 years old. There is a minority of linguists who believe that the Indo-European and Semitic language families descend from a prehistoric language ancestral to both, but I don't think this is accepted in the mainstream.

In any case, it's beyond speculative to try and connect these roots.
