Questions & Answers about Mi amiga no es antipática.
Does antipática mean "antipathetic"?
Why do we use es instead of está to say "is"?
Why does antipática end in an "a" here?
In Spanish, adjectives must match the gender of the noun they describe. Because we are talking about a female friend (amiga), the adjective must be in its feminine form: antipática. If this were a male friend, it would be Mi amigo no es antipático.
Why does no come before the verb instead of after it?
In Spanish, the negative word no always goes directly in front of the verb it changes. While English says "is not," Spanish essentially says "not is" (no es).
