So мати is mother, and мама is mum, mom, mummy (or any other less formal term for mother)?
We have even more words to talk about our moms.
- Mother = мати, матір - the most formal way
- Mom = мама, ненька - the latter is less common, however often used to speak about our Motherland "Україна-ненька"
- Mommy = матуся, матінка, мамця, неня - the least formal
Also тіточка, but the one written by SergioRuido is just so much more gentle and loving somehow ^^ At least for me. Like, I would call a woman on the street та тіточка or та тітка, but "тітонька" is quite warm :)
