Thank you all for your input, it has been most enlightening.
As Willvr pointed out I was just trying to differentiate by the two types of humans available as per the phb and trying to give them names in the same way that you have wood/high elves.
My original leaning was towards using ancient languages but Hominus (Latin) and Anthropos (Greek) didn't really feel right. Then I saw dirigible's post...
Dirigible:
The '+1 to all stats' humans might call themselves the True or Superior humans (or Prime, Ubermensch, Perfected, Pure, Ascended, Chosen, Favoured, Godborn, Cathar Perfecti, etc).
The '+1 to two stats and a feat' humans, being less physically and mentally gifted but more flexible and resourceful might call themselves the Cunning Folk, Masterly, the New Men, Ardent, Called...
I liked this a lot but wasn't sure on the names for the +1 to all, so I did a thesaurus search on prime and came up with cardinal.
So now I have my two sub races of human...
Cardinal Human: +1 to all stats
Ardent Human: +1 to 2 stats, 1 skill, 1 feat.
Thank you all again.
