Questions & Answers about Mi hermano es joven e independiente.
Why does the sentence use e instead of y for 'and'?
Would independiente change to end in 'a' if I was talking about my sister?
No, it stays exactly the same. Adjectives that end in -e in Spanish are gender-neutral. Whether you are talking about a brother (hermano) or a sister (hermana), you still use independiente.
Why do we use es instead of está? Isn't being young a temporary state?
