She not only does love her mother, she also does love her father.
In this sentence, does the word "does" emphasize the verb "love"?
Thanks a lot.

The answer may be incorrect in British English, but not US. Sorry.

What I need is your helpful answers, not your arguments between US English and British English.
Thank you all.

That is simply untrue. It is ungrammatical in both BrE and AmE.

It emphasises the existence of her love. One might use that sentence to dispel any doubt in someone's mind as to whether she really does love her father as well as her mother.
