Weather patterns, Monday's soon building (8)
I believe the answer is:
monsoons
'weather patterns' is the definition.
Although both the answer and definition are plural nouns, I can't understand how one could define the other.
'monday's soon building' is the wordplay.
'monday's' becomes 'mon's' (short for Monday).
'building' indicates an anagram.
'soon' with letters rearranged gives 'oons'.
'mons'+'oons'='MONSOONS'
Can you help me to learn more?
(Other definitions for monsoons that I've seen before include "Asian winds, can bring heavy rain" , "Winds in Asia, can bring heavy rain" .)
