Incorporated different diet when encouraged (7)
I believe the answer is:
incited
'encouraged' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe you can see a link between them that I don't see?
'incorporated different diet' is the wordplay.
'incorporated' becomes 'inc'.
'different' is an anagram indicator (letters placed in a different order).
'diet' anagrammed gives 'ited'.
'inc'+'ited'='INCITED'
'when' is the link.
Can you help me to learn more?
(Other definitions for incited that I've seen before include "Encouraged, stirred up" , "Egged on to action as in edict" , "Goaded into action" , "Provoked and urged on" , "was much encouraged" .)
