I know that in English I have to say "don't be shy" or "He is shy" etc. Always (at least for me) it is be + adjective. But I'm looking for the verb (or verbs) which denotes the same meaning and then I can use to + infinitive in the meaning which mentioned above.
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:
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As noted there are other less common, outdated usages: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
