Unravelling net, I'm so wet (7)
I believe the answer is:
moisten
'wet' is the definition.
(moistening is a kind of wetting)
'unravelling net i'm so' is the wordplay.
'unravelling' is an anagram indicator.
'net'+'im'+'so'='netimso'
'netimso' with letters rearranged gives 'MOISTEN'.
(Other definitions for moisten that I've seen before include "It's on me (anag)" , "contrary to sixteen down [DEHYDRATE]!" , "Make damp, say lips with tongue" , "What one's eyes may do!" , "water a bit" .)
