can you help with translating "to his merit"?

Question

I'm stuck.

Answer 1

Im sure you know but literrally it would be a su merito. whats the whole sentence though'

Answer 2

Yes, I know that is the literal translation, but it just does not sound right. THe context is "to his merit, he no longer behaves like that"

Answer 3

Perfect example of why giving context is so important.

Gustavo, is there any difference between portarse and comportarse?

Reminds me of something a friend used to tell me in Morelia:

-Pórtate bién, y si no te portas bién, invítame. jajaja

Answer 4

Muchas gracias por su ayuda!

Hope that helps.

Answer 6
