Form of elation that may be cut short (7)
I believe the answer is:
toenail
'form of elation that may be cut short' is the definition.
The definition and answer can be both body parts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'form of elation' is the wordplay.
'form of' indicates an anagram (the letters need to be in another 'form').
'elation' with letters rearranged gives 'TOENAIL'.
Can you help me to learn more?
(Other definitions for toenail that I've seen before include "Part of body perhaps painted" , "Footplate, perhaps" , "Digital cover-- 21 across (anag)" , "One's occasionally filed" , "A girl might paint this" .)
