Work around spilt rum, causing great agitation (7)
I believe the answer is:
turmoil
'great agitation' is the definition.
'turmoil' can be an answer for 'agitation' (synonyms). I'm unsure of the 'great' bit.
'work around spilt rum' is the wordplay.
'work' becomes 'toil' (toil is a kind of work).
'around' is an insertion indicator.
'spilt' indicates anagramming the letters.
'rum' with letters rearranged gives 'urm'.
'toil' enclosing 'urm' is 'TURMOIL'.
'causing' acts as a link.
Can you help me to learn more?
(Other definitions for turmoil that I've seen before include "Agitation, din, bustle" , "Brouhaha" , "upset" , "Chaos" , "State of great commotion or disturbance" .)
