Cease boiling pots (4)
I believe the answer is:
stop
'cease' is the definition.
(synonyms)
'boiling pots' is the wordplay.
'boiling' indicates anagramming the letters.
'pots' anagrammed gives 'STOP'.
(Other definitions for stop that I've seen before include "End or pause" , "Hold on" , "Knock out" , "as per instruction" , "Pause - prevent" .)
