Pastor meekly suppresses outburst (5)
I believe the answer is:
storm
'outburst' is the definition.
(I've seen this in another clue)
'pastor meekly suppresses' is the wordplay.
'suppresses' indicates a hidden word (the clue suppresses or covers up the answer).
'STORM' is hidden within 'pastor meekly'.
(Other definitions for storm that I've seen before include "Very unfavourable climate" , "SECOND PART OF 1 DOWN" , "Rumpus" , "Sandy, perhaps" , "Violent weather condition" .)
