Learn Russian: У меня есть два вопроса.

In Russian, the numbers 2, 3, and 4 don't take a normal plural noun. Instead, they must be followed by the genitive singular form of the noun. The dictionary form is вопрос (a masculine noun), and its genitive singular form is вопроса.

Why do we use два for "two" here instead of две?

The number "two" has two different forms depending on the gender of the noun it counts. We use два for masculine and neuter nouns, and две for feminine nouns. Because вопрос is a masculine noun, we must use два.

How exactly does У меня есть translate to "I have"?

Russian doesn't commonly use a direct verb for "to have" like English does. Instead, it uses this construction which literally means "By me there is." У means "by" or "at", меня is a form of я (I), and есть means "is" or "exists".

How do you pronounce the first "o" in вопроса?

It sounds like an "a". The stress in this word is on the second syllable (вопро́са). In Russian, whenever an "o" does not carry the stress, it is pronounced like an "a" (a rule called vowel reduction). So the word sounds like "va-PRO-sa".
