Do they loaf at their work? (6)
I believe the answer is:
bakers
'do they' is the definition.
The definition suggests a plural noun which matches the answer.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for bakers that I've seen before include "This dozen is thirteen" , "They make bread and cakes" , "9 makers" , "Unlucky number of loaves?" , "Bread-makers" .)
