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 quite see how this works, but
'a' is within the answer.
'trendy' could be 'in' ('in' can mean fashionable) and 'in' is present in the answer.
This explanation may well be incorrect...
'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" .)
