Rainy days appearing shortly after month (7)
I believe the answer is:
monsoon
'rainy days appearing shortly after month' is the definition.
I can't judge whether this definition defines the answer.
'appearing shortly after month' is the wordplay.
'appearing' becomes 'on' (e.g. on stage or on television).
'shortly' becomes 'soon' (synonyms).
'after' says to put letters next to each other.
'month' becomes 'M' (standard abbreviation).
'on'+'soon'='onsoon'
'onsoon' put after 'm' is 'MONSOON'.
Can you help me to learn more?
(Other definitions for monsoon that I've seen before include "Very heavy rainfall season" , "Rainy season in southern Asia" , "'Seasonal wind in southern Asia, brings heavy rains (7)'" , "A lot of rain, perhaps" , "Wild weather" .)
