Pursue communist making slow progress (7)
I believe the answer is:
dogtrot
'slow progress' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'pursue communist' is the wordplay.
'pursue' becomes 'dog' (dogging is a kind of pursuing).
'communist' becomes 'trot' (short for Trotskyist).
'dog'+'trot'='DOGTROT'
'making' acts as a link.
Can you help me to learn more?
(Other definitions for dogtrot that I've seen before include "Pace between walking and running" , "running at gentle pace" , "Gentle easy pace" , "Slowish running pace of canine analogy" , "Gentle paced run" .)
