Regretful after making case of rubber goods wet (5)
I believe the answer is:
soggy
'wet' is the definition.
(similar in meaning)
'regretful after making case of rubber goods' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'goods' could be 'gg' (an abbreviation for 'good' repeated) and 'gg' is located 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 soggy that I've seen before include "Soaked" , "Waterlogged" , "rather wet" , "Squelchy" , "Soft or heavy with moisture" .)
