monotonicadj.

Brit.

/ˌmɒnəˈtɒnɪk/, U.S.

/ˌmɑnəˈtɑnɪk/

Origin: Formed within English, by compounding. Etymons: mono- comb. form, tonic adj.

Etymology: < mono- comb. form + tonic adj., after monotone n. In sense 2 after German monoton (see monotone adj.). Compare earlier monotonical adj., monotonous adj.

1. Of, relating to, or uttered in a monotone; (of an instrument or a line of music) limited or confined to one tone or pitch.

1797 Encycl. Brit. XII. 538/2 The fundamental bass which in itself is monotonic and little suited for singing [etc.].

1828 N. Webster Amer. Dict. Eng. Lang. Monotonic, monotonous (little used).

1880 G. Grove Dict. Music II. 355/1 The use of Monotonic Recitation is of extreme antiquity.

1987 Melody Maker 8 Aug. 14/2 ‘Oh no, I don't want bits of a dead shark,’ he says in that monotonic whine.

1989 H. Cole Malcolm Arnold iv. 52 The new theme recedes into the background and is later reduced to a monotonic rhythm.

2. Mathematics and Science. Of a function of a real variable: varying so that as the value of the variable increases, the value of the function may increase but never decrease (a monotonic increasing function), or conversely may decrease but never increase (a monotonic decreasing function). Of a sequence: consisting of successive terms that may increase but never decrease in value, or conversely may decrease but never increase in value. Also: designating a variation in value that follows such a pattern. Cf. monotone n. 3, monotonous adj. 3.
