This is the 188th most frequent Ukrainian word.
дві
"Дві" means "two" (feminine form) in English.
The word 'дві' is used to indicate the numeral 'two' in feminine form due to the feminine gender of the noun 'машини'.
У нас є дві машини.
We have two cars.
Here, 'дві' accompanies the feminine plural noun 'дівчини', specifying the quantity.
Я бачу дві дівчини на вулиці.
I see two girls on the street.
In this example, 'дві' is used with the feminine plural form 'книги' to denote 'two books.'
