Etymology: "Gloweringly" is simply "glowering" with the adverbial suffix attached, and the suffix is the more ancient part of it. The "-ly" ending descends from an Old English "-līċe," which in turn goes back to a Proto-Germanic "-līkō" meaning "having the form or appearance of," the same root that gives English "like" and "-like" in words such as "godlike." So an adverb formed with "-ly" literally describes an action done in the manner of the base word. The base, "glower," is the more puzzling piece, and the source material does not trace it further than the Middle English-era chain of the suffix, so the verb's own history is best left aside here. What matters is that "glowering" describes a stare that looks hot and fierce, and "gloweringly" carries that expression into the manner of an action, as in a person who answers a question with a gloweringly lowered brow.
