Royal editor given a treat (7)
I believe the answer is:
regaled
'given a treat' is the definition.
The definition and answer can be both related to consumption as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'royal editor' is the wordplay.
'royal' becomes 'regal' (synonyms).
'editor' becomes 'ed' (abbreviation).
'regal'+'ed'='REGALED'
Can you help me to learn more?
(Other definitions for regaled that I've seen before include "wined and dined" , "Plied with drink" , "Feted" .)
