Brit.

/prᵻˈsɛs/, U.S.

/prəˈsɛs/

Origin: A borrowing from Latin. Etymons: Latin praecess-, praecēdere.

Etymology: < classical Latin praecess-, past participial stem of praecēdere precede v.² In sense 2 after precession n.² Compare earlier precede v.²

†1. transitive. To precede, to take precedence over. Obsolete. rare.

1892 A. M. Worthington Dynamics of Rotation xiii. 135 The application of the couple is said to cause the spinning wheel to ‘precess’.

1942 J. L. Synge & B. A. Griffith Princ. Mech. xiv. 418 A disk, 6 inches in diameter, is mounted on the end of a light rod 1 inch long and spins rapidly. It precesses once in 15 seconds.

1957 Endeavour Oct. 185/2 In each of these levels the nucleus precesses about the direction of H₀, but maintains its correct orientation in the field.

1985 Pract. Computing Oct. 85/1 If it is launched in an orbit about the poles, the orbits precess and the satellite is able to scan the entire surface of the globe, a segment at a time.

1998 T. McKenna in J. M. Jenkins Maya Cosmogenesis p. xxv Because the winter solstice node is precessing, it is moving closer and closer to the point on the ecliptic where it will eclipse the galactic center.

b. transitive. To cause to undergo precession; spec. to transform (astronomical coordinates) in a manner corresponding to the effects of the precession of the equinoxes.

1915 Man. Seamanship (rev. ed.) I. v. 175 If the compass is now left alone, the force of gravity acting on the titlted axis provides a couple precessing it back to the meridian again.

1979 Nature 20 Sept. 203/2 The principal effect of the oblateness is to slew or precess the particle orbit planes.

1992 S. P. Maran Astron. & Astrophysics Encycl. 35/1 The process of transforming from the coordinate system of one date to that of another is called precessing the coordinates.

1902 Science 6 June 909/2 The next effect is the lessening of the angle of the cone described by the precessing axis, an effect entirely analogous to the ‘sleeping’ of a common top.

1946 Trans. Amer. Math. Soc. 59 109 A short appendix deals with the similarities of the motions of a retrogradely precessing top and the spherical pendulum.
