Brief rest matters with walk to give respite (9,5)
I believe the answer is:
breathing space
'respite' is the definition.
(I know that breathing space is a type of respite)
'brief rest matters with walk' is the wordplay.
I cannot quite understand how this works, but
'rest' could be 'breath' (breath is a kind of rest) and 'breath' is located in the answer.
'walk' could be 'pace' (pacing is a kind of walking) and 'pace' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'to give' is the link.
Can you help me to learn more?
(Other definitions for breathing space that I've seen before include "relief" , "room" , "Brief respite" , "chance to relax" , "might give one an opportunity to relax" .)
