Original model of yacht peer adapted (9)
I believe the answer is:
archetype
'original model' is the definition.
(I've seen this in another clue)
'yacht peer adapted' is the wordplay.
'adapted' indicates anagramming the letters.
'yacht'+'peer'='yachtpeer'
'yachtpeer' with letters rearranged gives 'ARCHETYPE'.
'of' acts as a link.
(Other definitions for archetype that I've seen before include "Standard - cheap tyre (anag)" , "Very typical example" , "Original mode" , "Perfect example" , "They caper about like original model" .)
