Onset of duly damp weather requires channel for water (5)
I believe the answer is:
drain
'channel for water' is the definition.
'drain' can be an answer for 'channel' (thesaurus). I am not sure about the 'for water' bit.
'onset of duly damp weather' is the wordplay.
'onset of' indicates taking the first letters.
'damp weather' becomes 'rain' (rain is a kind of weather. I am not sure about the 'damp' bit.).
The initial letter of 'duly' is 'd'.
'd'+'rain'='DRAIN'
'requires' acts as a link.
Can you help me to learn more?
(Other definitions for drain that I've seen before include "Drink dry" , "Waste pipe" , "See 11 dn" , "ditch" , "Exhaust - pipe" .)
