Unpleasantly moist -- like seafood? (6)
I believe the answer is:
'unpleasantly moist' is the definition.
(I've seen this before)
'like seafood?' is the wordplay.
I cannot quite understand how this works, but
'like' could be 'y' (similar in meaning) and 'y' is located in the answer.
'seafood?' could be 'clam' (clam is a kind of seafood) and 'clam' is located in the answer.
A single letter 'm' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for clammy that I've seen before include "Wet and sticky" , "Moist and adhesive" , "Cold and damp" , "(Of weather) sticky" , "Dank" .)
