Questions & Answers about Tengo dos hermanos y tú tienes uno.
Why does the sentence end with uno instead of un?
In Spanish, uno is the number one. When it comes directly before a masculine noun, it drops the 'o' and becomes un (like un hermano). But here, because the word hermano is left out at the end of the sentence, it keeps its full form: uno.
Would the word dos change if I was talking about sisters instead of brothers?
What if I want to say 'I have two siblings' (a brother and a sister)?
You would still say tengo dos hermanos. In Spanish, the masculine plural is used whenever a group has a mix of males and females, so hermanos can mean 'brothers' or 'siblings'.
Why is there an accent mark on the word tú?
The accent mark shows the difference between two words that sound exactly the same. Tú (with the accent) means the pronoun 'you', while tu (without the accent) means 'your'.
