Having no change, uncle goes to the back of the queue (4)
I believe the answer is:
same
'having no change' is the definition.
I can't tell whether this defines the answer.
'uncle goes to the back of the queue' is the wordplay.
'uncle' becomes 'sam' (Uncle Sam is an example).
'goes to' says to put letters next to each other.
'the back of the' suggests the final letters.
The final letter of 'queue' is 'e'.
'sam'+'e'='SAME'
Can you help me to learn more?
(Other definitions for same that I've seen before include "Ditto" , "Identical, not different" , "Aforesaid" , "If - be the food of love, play on (Twelfth Night)" , "uniform" .)
