Fellow athlete's flying, taking drug and artificial body part (5,5)
I believe the answer is:
false teeth
'artificial body part' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'fellow athlete's flying taking drug' is the wordplay.
'fellow' becomes 'f' (abbreviation - of a society etc.).
'flying' indicates an anagram (letters fly around into new positions).
'taking' is an insertion indicator.
'drug' becomes 'e' (E is another name for ecstasy).
'f'+'athletes'='fathletes'
'fathletes' anagrammed gives 'falsteeth'.
'falsteeth' going around 'e' is 'FALSE TEETH'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for false teeth that I've seen before include "New gnashers!" , "Denture's components" , "Plates" , "set out at night" , "Choppers that may be taken out" .)
