Main demo swirled around hospital, directed at individual (2,7)
I believe the answer is:
ad hominem
'directed at individual' is the definition.
The definition suggests an adjective which matches the answer.
'main demo swirled around hospital' is the wordplay.
'swirled' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'hospital' becomes 'H' (abbreviation for hospital).
'main'+'demo'='maindemo'
'maindemo' with letters rearranged gives 'adominem'.
'adominem' enclosing 'h' is 'AD HOMINEM'.
Can you help me to learn more?
(Other definitions for ad hominem that I've seen before include "to man personally" , "(Of an argument) personal rather than objective (Latin)" , "Directed at particular person" , "Latin phrase for argument that attacks opponent rather than debates the issue" , "Relating to particular individual" .)
