Old narrator’s arrangement to contain stress via additional flex (9,4)
I believe the answer is:
extension cord
'old narrator's arrangement to contain stress via additional flex' is the definition.
I can't tell whether this definition defines the answer.
'old narrator's arrangement to contain stress via additional flex' is the wordplay.
I cannot really understand how this works, but
'old' could be 'ex' (prefix meaning former or onetime) and 'ex' is found within the answer.
'stress' could be 'tension' (synonyms) and 'tension' is located in the answer.
'flex' could be 'cord' (I've seen this before) and 'cord' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
