Granted a measure to identical twins (7)
I believe the answer is:
acceded
'granted' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'a measure to identical twins' is the wordplay.
'measure' becomes 'cc' (cc is a kind of measure).
'to identical twins' becomes 'eded' (I can't explain this - if you can you should believe this answer much more).
'a'+'cc'+'eded'='ACCEDED'
Can you help me to learn more?
(Other definitions for acceded that I've seen before include "Yielded to another's wishes" , "Consented to" , "Assented" , "Agreed to demand" , "'Agreed, acquiesced (7)'" .)
