City pal's set up is true to form (7)
I believe the answer is:
typical
'is true to form' is the definition.
(thesaurus)
'city pal's set' is the wordplay.
'set' is an anagram indicator (instruction to set the letters).
'city'+'pal'='citypal'
'citypal' with letters rearranged gives 'TYPICAL'.
'up' acts as a link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for typical that I've seen before include "routine" , "Normal" , "Clay pit (anag)" , "Having the essential characteristics of a group" , "Representative, standard" .)
