The word menacingly is an adverb.
The definition of menacingly is being with the intent of harming.
The sentence from the text is, "To her, the youngish black man-a broad six feet two inches with a beard and billowing hair, both hands shoved into the pockets of a bluky military jacket-seemed menacingly close."
My context clue that before that sentence, the author tells how he could have sworn he wasn't walking too close to the lady. Then the next one says how obviously, she thought that because of the way he looked, he was too close to her. Like in the movie, "Dennis the Menace"... Dennis was a dangerous boy to be around.
Its antonym would be, (peacefully) walking near someone.
Its synonym would be, in a threatenly fashion or position.
My original sentence is: The meteor seemed menacingly close to earth.
