Thank you so much, i got it. Could you plz clear the meaninig (of dummy here) and casese in which i can use the dummy auxiliary. Dose it mean that this auxiliary has no function within the sentence?
Thanks a lot for being cooperative
That's correct. "dummy" means that the auxilliary DO doesn't carry syntactic, or structural meaning. In other words, it is not required by the grammar; the sentence is grammatical with or without DO. But it does (in fact)have a semantic function. It serves as emphasis.
Thank you so much. I do understand your great explanation. Just i wanna know if there any additional cases (othe than emphasising) in which i can use that "dummy".
I'm really so greatful to find that great fourm.
