Ball's on the end of leg, perhaps in suspension (5)
I believe the answer is:
limbo
'in suspension' is the definition.
The answer and definition can be both states of affairs as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'ball's on the end of leg' is the wordplay.
'ball' becomes 'o' (letter resembling a ball).
'on' is a charade indicator (letters next to each other).
'the end of leg' becomes 'limb' (I can't justify this - if you can you should believe this answer much more).
'o' after 'limb' is 'LIMBO'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for limbo that I've seen before include "Period of uncertainty" , "Medieval Christian abode for unbaptised souls" , "Caribbean dance - place for lost souls" , "(Between) two extremes" , "Under-bar dance" .)
