Please consider the following sentence:
Once the people are disillusioned by blatant mischief-making, it becomes increasingly difficult to dazzle them, however impressive the lies.
1. What is the element "however impressive the lies" called in grammatical term?
2. Does "however" in the sentence function as a conjunction?
3. Can the element in (1) be moved around in the sentence?
I'm sorry that I may ask too many questions but this construction is interesting.
