"Один рік, два роки, п'ять років"

Translation: One year, two years, five years

[lualrija57]

why does "years" is write in two different ways?

[Dasintro]

It's grammatical idiom:

"роки" (Nominative plural) - with numerals that end with 2,3,4
"років" (Genitive plural) - with numeral that end with 5,6,7,8,9,0

[nadine29]

No sound for sentence.

[analystphilomath]

same for me :(
