Foolhardy in spots (4)
I believe the answer is:
rash
This clue is a double definition.
'foolhardy' is the first definition.
('rash' can be a synonym of 'foolhardy')
'spots' is the second definition.
(I've seen this before)
'in' acts as a link.
(Other definitions for rash that I've seen before include "complaint" , "Headstrong" , "Impetuous; skin ailment" , "Hasty; skin disorder" , "Red area on skin" .)
