Get back, for example, into shower (6)
I believe the answer is:
regain
'get back' is the definition.
(I've seen this before)
'example into shower' is the wordplay.
'example' becomes 'eg'.
'into' indicates putting letters inside.
'shower' becomes 'rain' ('rain shower' can be a synonym of 'shower').
'eg' going into 'rain' is 'REGAIN'.
'for' acts as a link.
(Other definitions for regain that I've seen before include "Get back, recover the use of" , "Recover - in gear (anag)" , "Recover, retrieve" , "Get back (previously owned object)" , "Win back" .)
