Bootlegging, excluding number that's suggestive (4)
I believe the answer is:
racy
'suggestive' is the definition.
(I've seen this before)
'bootlegging excluding number' is the wordplay.
I cannot quite understand how this works, but
'number' could be 'c' (C is an example) and 'c' is located in the answer.
The remaining letters 'ray' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for racy that I've seen before include "Risqu" , "Suggestive; spirited" , "rather blue" , "Slightly indecent" , "Lively" .)
