Not bad playing the role in "The Catalogue" (9)
I believe the answer is:
tolerable
'not bad' is the definition.
(thesaurus)
'playing the role in the catalogue' is the wordplay.
'playing' is an anagram indicator.
'in the' means one lot of letters goes inside another.
'catalogue' becomes 'table' (I am not sure about this - if you are sure you should believe this answer much more).
'role' is an anagram of 'oler'.
'oler' going within 'table' is 'TOLERABLE'.
Can you help me to learn more?
(Other definitions for tolerable that I've seen before include "Passable" , "Fairly good" , "Bearable" , "Acceptable" , "may be accepted?" .)
