What does Esta contenta ahora mean in spanish?

If you were to translate it Word for Word it would be "this happy now". It would help to know if you read it or heard it because the ret of the context would be able to help you figure out what it would mean in proper English. Hope I helped a bit :)

I suspect 'esta' should have an accent on the 'a', in which case it means 'is/are', depending on the (unspecified) related subject pronoun. Thus it could be:

Esta (ella) contenta ahora = Is she happy now

Esta (usted) contenta ahora = Are you (formal, singular, female) happy now

Since the final punctuation is also unclear, it may be an assertion, in which case:

(She) is happy now

(You, formal, singular, female) are happy now. (This is less likely)
