Personal pronouns get an «н» if preceded by a preposition. Think a/an in English.
Is that only the case if they start with a vowel as well?
If I said «У меня есть вода» then меня would stay the same.
Yes, all the 3rd person pronouns start with a vowel and that is how the rule is applied. As I found, "Pronouns that start with vowels may be proceeded by the letter "н" when used with some prepositions."
what norrius says :)
gen. У него / у неё / у них.
dat. К нему / к ней / к ним.
inst. С ним / с ней / с ними.
pre. О нём/о ней/ о них
наш is applied when the following noun is masculine and нашe when it's neutral.
It actually can be. There is a verb "to have" in Russian. But, it's a culture thing. An example for, let's say, English-speaking people in the USA: saying "motion picture" instead of "movie" or "film" used to be a thing. Now, if used by a person at all, it's used very seldom. "Movie" and "Film" took over as the two words that the vast majority of people ever say; our culture changed. The whole "u ... est'" thing must have become so popular that it became the norm.
tl;dr You can say the sentence like that and you would be understood, it would just sound weird to most people.
They have water, Get em boys! rustle and chanting of plumbers in the distance
Cant you just say “Hnx boda”? like you say “where train”n stuff like that
