Recovers, for example, in periods of wet weather (7)
I believe the answer is:
regains
'recovers' is the definition.
('regain' can be a synonym of 'recover')
'example in periods of wet weather' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'in' is an insertion indicator.
'periods of wet weather' becomes 'rains' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'eg' inserted within 'rains' is 'REGAINS'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for regains that I've seen before include "Wins back" , "Gets back" .)
