A trendy individual, as is typical (2,9)
I believe the answer is:
in character
'is typical' is the definition.
(I've seen this before)
'a trendy individual' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'trendy' could be 'in' ('in' can mean fashionable) and 'in' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
'as' acts as a link.
Can you help me to learn more?
(Other definitions for in character that I've seen before include "Dressed for the part" , "Appropriate for the part" , "True to type" , "Typical" .)
