Weekend nearly over? It's very wet weather (7)
I believe the answer is:
monsoon
'wet weather' is the definition.
(thesaurus)
'weekend nearly over? it's very' is the wordplay.
I cannot quite understand how this works, but
'over?' could be 'on' (physically on top of) and 'on' is located in the answer.
'very' could be 'so' (both can mean 'extremely') and 'so' is found within the answer.
The remaining letters 'mon' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for monsoon that I've seen before include "Seasonal wind and rain in S Asia" , "Very heavy rainfall season" , "Asian wind; rainy season" , "Wild weather" , "Season of heavy rain" .)
