Dominate

It's the oddest things that come to you when working out.

*dheigh- "shape"
*dhgh-óm "something to do with shaping" -> "earth"

*Nd- (Latin in-, end-o, ind-u, ind-a:go:, ind-ipiscor) "interior"
*Nd-óm- -> dóm- "something to do with the interior" -> "house; master"

dm- becomes nm- ín the "house" word in some languages.

That should explain that /o/.
