Little piggy’s end not a lie, tragically (7)
I believe the answer is:
toenail
'little piggy's end' is the definition.
(reference to This Little Piggy nursery rhyme)
'not a lie tragically' is the wordplay.
'tragically' indicates an anagram (I've seen this in other clues).
'not'+'a'+'lie'='notalie'
'notalie' anagrammed gives 'TOENAIL'.
(Other definitions for toenail that I've seen before include "Growth from foot" , "may need this cut?" , "part of leg" , "One of ten" , "woman in labour" .)
