Figures there's "no" loss to a navvy, outwardly! (5)
I believe the answer is:
fives
'figures' is the definition.
The definition and answer can be both quantities as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for fives that I've seen before include "horse disease as before" , "bunch capable of causing injury?" , "Small numbers" , "Game similar to squash" , "Ball game" .)
