Typical architect's car I wrecked (14)
I believe the answer is:
characteristic
'typical' is the definition.
(I've seen this before)
'architect's car i wrecked' is the wordplay.
'wrecked' is an anagram indicator.
'architects'+'car'+'i'='architectscari'
'architectscari' anagrammed gives 'CHARACTERISTIC'.
(Other definitions for characteristic that I've seen before include "Feature, quality" , "Distinctive" , "Trait" , "Typical (of a person or thing)" , "Typical of a particular person" .)
