Tū'mor, n.

n. [Lat. tumor, from tumere, to swell; It. tumore, Sp. tumor, Fr. tumeur.]

1. (Med.) A morbid swelling, prominence, or growth, on any part of the body.
2. Affected pomp; bombast in language; swelling words or expressions; false magnificence or sublimity. [Rare.]

Better, however, to be a flippant, than, by a revolting form of tumor and perplexity, to lead men into habits of intellect such as result from the modern vice of English style. De Quincey.
