You can take out "the," or you can continue the sentence like this: "Of the two girls, I found Lucy the better one." I hope that helps!

"the better" Also, out of context, that seems like a *very* insulting thing to say about the other girl. Perhaps in the paragraph you've limited it to a certain activity or certain quality, but if you just said that sentence, I wouldn't question your grammar, I would question your personality.

No, you cannot omit "the". You are referring to "the better of the two". It is required. This is awkward: Of the two girls, I found Lucy the better. This would be more natural: Of the two girls, I found Lucy to be the better of the two.

hi helen. i dont know how you begin your sentence. you can also say, among the two girls, i found lucy the better one.
