Questions & Answers about Мои сыновья и дочери читают вместе.
Why is the word for sons сыновья instead of following the normal plural rules?
You are right to notice that! The singular word for son is сын. Instead of just adding a normal plural ending like -ы, this word changes its ending completely to сыновья. This is a highly common irregular plural, just like how брат (brother) becomes братья and друг (friend) becomes друзья.
How does the word дочери (daughters) get its plural form?
The singular is дочь. It is a special feminine word. When making it plural, a hidden -ер- gets added into the middle of the word before the plural -и ending, making it дочери. You will see this exact same pattern with мать (mother), which becomes матери in the plural.
Why does the sentence start with Мои instead of Мой?
Мои is the plural form of the word for my. In Russian, possessive words must match the noun they describe. Since we are talking about multiple people (sons and daughters), the plural form is required. If it were just one son, you would use the masculine singular Мой сын.
Why does the verb читают end in -ют?
