Swelling

denotes "a puffing up, swelling with pride" (akin to phusioo, "to puff up"), 2Co 12:20, "swellings."

an adjective denoting "of excessive weight or size," is used metaphorically in the sense of "immoderate," especially of arrogant speech, in the neuter plural, virtually as a noun, 2Pe 2:18, Jud 1:16, "great swelling words," doubtless with reference to gnostic phraseology.
