Unusually wide? (5)
I believe the answer is:
extra
This clue is a double definition.
'unusually' is the first definition.
(I've seen this before)
'wide?' is the second definition.
(cricket, extra awarded for wide ball)
(Other definitions for extra that I've seen before include "More than usual" , "Ancillary" , "comes to 16 [TEST MATCH]" , "Unnecessary" , "Additional - run - actor - newspaper edition" .)
