Terrible catastrophe... food is distributed outside entrance to Gurudwara by Bill (3,2,3)
I believe the answer is:
act of god
'terrible catastrophe' is the definition.
The definition and answer can be both types of natural phenomena as well as being singular nouns.
Maybe there's an association between them I don't understand?
'food is distributed outside entrance to gurudwara by bill' is the wordplay.
'is distributed' indicates anagramming the letters.
'outside' means one lot of letters goes inside another.
'entrance to' says to take the initial letters.
'by' means one lot of letters go next to another.
'bill' becomes 'act' (I've seen this in other clues).
The first letter of 'gurudwara' is 'g'.
'food' with letters rearranged gives 'ofod'.
'ofod' enclosing 'g' is 'ofgod'.
'ofgod' after 'act' is 'ACT OF GOD'.
Can you help me to learn more?
(Other definitions for act of god that I've seen before include "An uncontrollable natural event, say an earthquake" , "Event outside human control" , "Uncontrollable natural event like earthquate" , "Unforeseeable accident" , "Event not caused by human error" .)
