Does putting дома in a sentence really change the position of the stress from the second syllable to the first?
Depends on if its genetive singular or nominitive plural. If its genitive singular (or the adverb, до́ма, meaning at home) then the stress is on the first vowel, if its nominative plural then its on the second, дома́
Is it the same than наше дома? Because наш means "our", this what I've learned so far :s
