Recovered from an excess (4)
I believe the answer is:
over
This clue could be a double definition.
'recovered from' is the first definition.
(as in being over an illness)
'an excess' is the second definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
Can you help me to learn more?
(Other definitions for over that I've seen before include "Finished like round of bowling in cricket" , "Finished like bowling session" , "Accomplished" , "Finished - across - in excess" , "Finished like cricket session" .)
