Michael777: The Spanish sentence asks for the adjective best, not better.
'Best' is the adjective describing something as 'good to the greatest extent'. 'Better' describes something as 'good to a greater extent' (but not as good as best).
Hope this helps.
But, "el mejor" means "the best." I think you say "Este regalo es el mejor" if you want to compare only two.
Please forgive the error in my previous response. I think you say "Este regalo es mejor que [whatever the other is]," NOT what I wrote before! (In other words, if "el" is associated with "mejor," the translation is "the best," not "the better.")
For "the better girl," I think it could at least be "Ella es mejor que . . . ." There has to be a more succinct way, I just don't know it. I hope someone more knowledgeable will repond to us.
Muchas Gracias para la clarificación. Yo tiene una mejor entendemiento ahora.
Mejor translates most directly to BETTER, and make a perfect sentence in English. Especially when comparing 2 gifts
I don't know if it is my speaker sound or my poor listening skills, but sometimes I have trouble telling the difference between words like "este" and "esta'' when in a sentence. In general, this would be "este" unless it was referring to a feminine word. Duo does it different ways. I would like others to tell me what their experience is.
