Is able to lift a ton, yet evidently fails (6)
I believe the answer is:
cannot
'evidently fails' is the definition.
I can't tell whether this defines the answer.
'is able to lift a ton' is the wordplay.
'is able to' becomes 'can' (if you can do something you are able to do it).
'lift' shows that the letters should be reversed in order.
'ton' backwards is 'not'.
'can'+'not'='CANNOT'
'yet' acts as a link.
Can you help me to learn more?
(Other definitions for cannot that I've seen before include "Is unabe to" , "Canton (anag.)" , "Is not able to" , "Is unable to" , "Defeatist's word?" .)
