Rodent going around had travelled from residence synonymous with the Tea Party (8)
I believe the answer is:
madhouse
'residence synonymous with the tea party' is the definition.
I can't judge whether this defines the answer.
'rodent going around had travelled' is the wordplay.
'rodent' becomes 'mouse' (mouse is a kind of rodent**).
'going around' is an insertion indicator.
'travelled' indicates an anagram.
'had' anagrammed gives 'adh'.
'mouse' going around 'adh' is 'MADHOUSE'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for madhouse that I've seen before include "pandemonium?" , "State of uproar and total confusion" , "9d 21d [BEDLAM]" , "state of chaos" , "badly run establishment?" .)
