Shared the same view about old houses (6)
I believe the answer is:
agreed
'shared the same view' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'about old houses' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'old' becomes 'aged' (similar in meaning).
'houses' is an insertion indicator.
're' inserted within 'aged' is 'AGREED'.
Can you help me to learn more?
(Other definitions for agreed that I've seen before include "Of one mind" , "OK, fine!" , "It's a deal!" , "I'll go along with that" , "ratified" .)
