What is bigly?

"Bigly" is an adverb that gained popularity during the 2016 U.S. presidential campaign, particularly through its use by Donald Trump. Although it is often interpreted as a variation of "big" or "greatly," its grammatical correctness has been debated. The term has since been used in various contexts, sometimes humorously, to emphasize the magnitude of something. Its usage reflects the blending of informal speech with political discourse.
