I'm a little stuck... Click here to teach me more about this clue!

'get back' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for regain that I've seen before include "Get back, recover the use of" , "Win back" , "Take back (the Ashes, for example)" , "Possess once more for regina" , "Recover - in gear (anag)" .)

I've seen this clue in The Independent.
