Row about new tempo initially elevated stress (7)
I believe the answer is:
tension
'stress' is the definition.
(I know that tension is a type of stress)
'row about new tempo initially elevated' is the wordplay.
I cannot quite see how this works, but
'about' could be 'on' (as in a book 'on' a certain topic) and 'on' is found within the answer.
'new' could be 'n' (abbreviation as in New Testament NT) and 'n' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for tension that I've seen before include "Stretched, uneasy, condition" , "A pulling strain" , "Uneasiness" , "Anxiety" , "Strained state" .)
