End of stay after prison sentence able to be lengthened (8)
I believe the answer is:
stretchy
'able to be lengthened' is the definition.
I can't judge whether this definition defines the answer.
'end of stay after prison sentence' is the wordplay.
'end of' says to take the final letters.
'after' is a charade indicator (letters next to each other).
'prison sentence' becomes 'stretch' (I've seen this in another clue).
The last letter of 'stay' is 'y'.
'y' after 'stretch' is 'STRETCHY'.
Can you help me to learn more?
(Other definitions for stretchy that I've seen before include "Of variable length, perhaps" , "Flexible" , "Elastic" .)
