oscillatev.

Brit.

/ˈɒsᵻleɪt/, U.S.

/ˈɑsəˌleɪt/

Origin: A borrowing from Latin. Etymons: Latin ōscillāt-, ōscillāre.

Etymology: < classical Latin ōscillāt-, past participial stem (compare -ate suffix³) of ōscillāre to swing < oscillum (or ōscillum ) something that moves to and fro, a swing, of unknown origin (see note). Compare French osciller (1751). Compare earlier oscillation n.It has been suggested that classical Latin oscillum (or ōscillum ) a swing represents a spec. use or development of ōscillum a small mouth (in botanical use), a small face (applied to a mask left to swing in the breeze) < ōs mouth (see oral adj.) + -cillum, neuter of -cillus, diminutive suffix.

a. intransitive. To swing backwards and forwards; to move to and fro between two points; to vibrate.

1757 E. Burke Philos. Enq. Sublime & Beautiful iv. §12. 136 Move any body, as a pendulum, in one way, and it will continue to oscillate in an arch of the same circle, until the known causes make it rest.
