Yell about critic oddly finding a quicker route (5,3)
I believe the answer is:
short cut
'a quicker route' is the definition.
(I've seen this before)
'yell about critic oddly' is the wordplay.
'yell' becomes 'shout' ('shout' can be a synonym of 'yell'**).
'about' indicates putting letters inside.
'oddly' indicates alternate letters.
The alternate letters of 'critic' are 'rtc'.
'shout' placed around 'rtc' is 'SHORT-CUT'.
'finding' is the link.
(Other definitions for short cut that I've seen before include "easy way" , "number 1?" , "Route saving time and distance" , "Time-saving manoeuvre" , "Quick way" .)
