A chap good to have in a bit of trouble (5)
I believe the answer is:
bloke
'a chap' is the definition.
(I know that chap can be written as bloke)
'good to have in a bit of trouble' is the wordplay.
I cannot really see how this works, but
'good' could be 'ok' and 'ok' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for bloke that I've seen before include "British fellow or chap" , "Chap, man" , "Fellow (informal)" , "Chap, lad" , "Geezer" .)
