Wet through and through (6)
I believe the answer is:
sodden
'wet through and through' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sodden that I've seen before include "Totally saturated" , "'Soaked, sopping (6)'" , "Soaking wet" , "Muddy" , "heavy with moisture" .)
