One earning crust from bread engages right tout (6)
I believe the answer is:
barker
'tout' is the definition.
(I've seen this before)
'one earning crust from bread engages right' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is found within the answer.
'right' could be 'r' (common abbreviation) and 'r' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for barker that I've seen before include "setter, perhaps" , "Loud showman and dog" , "One stands at a carnival giving loud, colourful, sales talk" , "Tout" .)
