regaled

'given a treat' is the definition.
The definition and answer can be both related to consumption as well as being past participle verbs.

'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" .)
