Learn English – Verb for what the radio does

To sum up:

The verb to shy is used to express a sudden movement especially of an animal:

(shies, shying, shied, shied BrE /ʃaɪd/ ; NAmE /ʃaɪd/)

• [intransitive] shy (at something) (especially of a horse) to turn away with a sudden movement because it is afraid or surprised:

  • My horse shied at the unfamiliar noise. Her horse shied violently at a gorse bush.

But probably its more common usage is in the idiomatic expression:

shy away (from something):

• to avoid doing something because you are nervous or frightened:

  • Hugh never shied away from his responsibilities. The newspapers have shied away from investigating the story.

As noted there are other less common, outdated usages:

• "to throw (a missile) with a jerk or toss," 1787, colloquial, of unknown origin and uncertain connection to shy (adj.).

• "to recoil," 1640s, from shy (adj.).

Note also the expression coconut shy:

• a game at a fair where you throw balls at a row of coconuts and try to knock them down to win them
