What a cloud burst may do when some children go to church (6)
I believe the answer is:
drench
'to church' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'what a cloud burst may do when some children' is the wordplay.
I cannot really understand how this works, but
'children' could be 'ch' (genealogical abbreviation) and 'ch' is found in the answer.
This explanation may well be incorrect...
'go' is the link.
Can you help me to learn more?
(Other definitions for drench that I've seen before include "Steep, soak" , "Soak or saturate" , "Soak, dowse" , "Wet thoroughly, soak" , "Soak, souse" .)
