Possesive pronoun 'můj'
I wonder if it matters if you say 'moji' or 'mí' if it's Nom. Pl. and the same with 'moje' and 'mé' if it's Acc. Pl. Does anyone know. Just the question if it's the same or have any difference.
It is the same. Sometines one may sound better in certain combination for rhytmical reasons or may be easier to pronounce, but they should be fully interchangeable.
