Questions & Answers about Jadę dzisiaj do miasta z dwojgiem bliźniąt.
Why do we use the collective numeral dwojgiem instead of the standard instrumental numeral dwoma here?
The noun bliźnięta (twins) refers to the young of humans or animals, which typically have the suffix -ęta in the plural. This specific group of nouns requires collective numerals like dwoje rather than standard numbers. Because the preposition z (with) dictates the instrumental case, dwoje changes to its oblique form dwojgiem.
The preposition z means "with" and takes the instrumental case. Why is bliźniąt in the genitive case instead of the instrumental?
This is one of the trickiest rules of oblique collective numerals! When a collective numeral is in the instrumental case (like dwojgiem), it does not agree in case with the noun. Instead, it forces the following noun into the genitive plural. That is why we pair the instrumental dwojgiem with the genitive bliźniąt.
What is the base form of bliźniąt and how does it become this genitive plural form?
The nominative singular is bliźnię (a twin), and the nominative plural is bliźnięta. To form the genitive plural for these specific types of "young" nouns, you drop the final -a and change the nasal vowel ę to ą, resulting in bliźniąt.
In everyday speech, is there a more common way to say this without using the complex collective numeral dwojgiem?
Yes! Native speakers frequently replace collective numerals with feminine numeral nouns like dwójka in casual conversation. You could say z dwójką bliźniąt. Since dwójka is a noun, it declines regularly in the instrumental (z dwójką) and naturally takes the genitive plural (bliźniąt) after it.
