Fat misshapen toe’s torn gym clothing (7)
I believe the answer is:
leotard
'fat' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's a link between them I don't understand?
'misshapen toe's torn gym clothing' is the wordplay.
'misshapen' indicates anagramming the letters.
'torn gym' becomes 'lard' (I can't justify this - if you can you should give a lot more credence to this answer).
'clothing' indicates putting letters inside (some letters cover up or clothe others).
'toe' is an anagram of 'eot'.
'eot' going inside 'lard' is 'LEOTARD'.
Can you help me to learn more?
(Other definitions for leotard that I've seen before include "Acrobat costume" , "Gymnastic garment" , "Do alter for acrobat's garment" , "Dance garment" , "One-piece exercise garment" .)
