Told to fold again when full (7)
I believe the answer is:
replete
'full' is the definition.
(I know that full can be written as replete)
'told to fold again when' is the wordplay.
I cannot really see how this works, but
'again' could be 're' (prefix meaning 'again') and 're' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for replete that I've seen before include "unable to take any more" , "Filled to satiety" , "Gorged, satiated" , "Well-supplied" , "Filled, well supplied" .)
