Broken bread, say (5)
I believe the answer is:
eaten
'broken bread say' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'broken' is the wordplay.
I cannot quite see how this works, but
'broken' could be 'ate' (eating is a kind of breaking) and 'ate' is located in the answer.
The remaining letters 'en' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eaten that I've seen before include "used for food" , "Swallowed" , "Scoffed" , "dinners should be" , "This bread is soon forgotten, it's said" .)
