Halts but still makes progress (5)
I believe the answer is:
limps
'halts' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for limps that I've seen before include "Hobbles" , "Walks haltingly" .)
