Communicated and left one aside, broken (7)
I believe the answer is:
liaised
'communicated' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'left one aside broken' is the wordplay.
'left' is a reversal indicator.
'one' becomes 'il' (I can't explain this - if you can you should believe this answer much more).
'broken' is an anagram indicator.
'il' backwards is 'li'.
'aside' with letters rearranged gives 'aised'.
'li'+'aised'='LIAISED'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for liaised that I've seen before include "Networked" , "got in touch" , "consulted together" , "Established contacts" , "Maintained contact" .)
