Endure expression while having the final say (4,4)
I believe the answer is:
last word
'the final say' is the definition.
(I've seen this in another clue)
'endure expression while' is the wordplay.
I cannot quite see how this works, but
'endure' could be 'last' (synonyms) and 'last' is found within the answer.
'expression' could be 'word' and 'word' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'having' is the link.
Can you help me to learn more?
(Other definitions for last word that I've seen before include "It's state-of-the-art" , "Amen" , "Dernier cri" , "Final remark in argument" , "Final statement in dispute, often decisive" .)
