It supports progress with conscious pride (5)
I believe the answer is:
strut
This might be a double definition.
'it supports progress' is the first definition.
The definition suggests a singular noun which matches the answer.
'conscious pride' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'with' is the link.
Can you help me to learn more?
(Other definitions for strut that I've seen before include "Walk proudly, swagger" , "Walk proudly like metal support" , "parade" , "supporter" , "Rigid support" .)
