Dishes delayed in case of prayers (6)
I believe the answer is:
plates
'dishes' is the definition.
(plate is a kind of dish)
'delayed in case of prayers' is the wordplay.
'delayed' becomes 'late' (I've seen this before).
'in' indicates putting letters inside.
'case of' suggests removing the centre (outsides of).
'prayers' with its middle taken out is 'ps'.
'late' put within 'ps' is 'PLATES'.
(Other definitions for plates that I've seen before include "They're on the table" , "Strange staple for crockery items" , "Eating utensils of staple kind" , "Flat dishes" , "Staple for food containers" .)
