Throw tea about causing trouble (3,5)
I believe the answer is:
hot water
'trouble' is the definition.
(to get in hot water is to get in trouble)
'throw tea about' is the wordplay.
'about' is an anagram indicator.
'throw'+'tea'='throwtea'
'throwtea' is an anagram of 'HOT WATER'.
'causing' is the link.
(Other definitions for hot water that I've seen before include "A state of trouble" , "Kind of trouble, could be scalding" , "Trouble - put the kettle on" , "(Liquid) trouble!" , "Bed warmer" .)
