Por muy mono...

Question

Por muy mono que fuera no iba a permitir que utilizara ese diminutivo y...

someone has just called her by a shortened version of her name that she didn't like and she said...

What a monkey; I'm not going to allow you to use that diminutive and....

or have I got hold of the wrong end of the stick here?

In this case, mono mean pretty, lovely. In other cases mono also mean nice and cute. - Pablo_Zamarro, Jul 19, 2013

Answer 1

I think it's as Lagartija says but perhaps referring to the girl:

Sweet as she was, ( however sweet she may have been) she was not going to let herself be called by that insulting diminutive version of her name..

Without further context it's a bit hard to say!

That is perfect, annierats. They last met when she was little (and cute) so I think it is something like, no matter how cute she had been, she wasn't going to let him use that short version of her name. - togtog, Jul 19, 2013

That sounds likely. Thanks for giving context. - annierats, Jul 19, 2013

Answer 2

Here in Spain mono/a is usually used in a positive approving context. A common example is when a clutch of woman gather round a pram, you'll hear:

¡Que mono es! ...Ay que mona etc.

So |I'm guessing the meaning here is something like

"As nice as it was.... (sounds)and ... I'm not going to accept ...and so on
