Eastern Armenian question: What does the "ի" at the end of the word means? Like հացուստ vs հացուստի or փողոցա vs փողոցի ? Thanks!

The letter ր changes it's sound Hi, I was wondering about the letter ր and the way it sounds at the end of a word. I found 3 words that end with ր and it has 3 different sounds (to my ear): t, r, sh հայր - ր sounds like t դուստր - ր sounds like r ջրնարար - ր sounds like sh Is it really that the letter sounds different? Or is it just a matter of pronouncing? Thanks, TlalitThanks Kasper, All of the ր sound the same in Armenian??? I am listening to a recording of those words and they sound so different in each of the words above. I fixed the last word that you told me to check its spelling. It's supposed to mean "a builder" maybe? ջինարար and in the recording it sounds like : Shinarash. How would you pronounce it? Thanks, Tlalit
