Maybe fish finger's striking part of Drake's outfit? (8)
I believe the answer is:
codpiece
'drake's outfit?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'maybe fish finger's striking part' is the wordplay.
I cannot quite see how this works, but
'fish' could be 'cod' (type of fish) and 'cod' is found in the answer.
'part' could be 'piece' (piece is a kind of part) and 'piece' is found in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for codpiece that I've seen before include "Medieval male accoutrement for the nether regions" , "for promotion of virility?" , "What kept privates in place" , "Male dress item of former times" , "men put on centuries ago" .)
