Gradation

 

a stylistic device; a series of similar words or expressions (images, similes, metaphors, and so on) that gradually emphasize and increase or, on the other hand, decrease (climax and anticlimax, respectively) the sense or emotional significance. The principle of gradation may be the device in a verse composition (in lyric poetry—for example, “The east grew white ...” by F. I. Tiutchev) or plot composition (byliny [epic folk songs] or fairy tales—for example, The Little Tower Chamber). An example of stylistic climactic gradation is “I do not regret, I do not call, I do not cry” (S. A. Esenin).
