Get heard abroad, and understood (8)
I believe the answer is:
gathered
'understood' is the definition.
('gather' can be a synonym of 'understand')
'get heard abroad' is the wordplay.
'abroad' indicates an anagram.
'get'+'heard'='getheard'
'getheard' is an anagram of 'GATHERED'.
'and' is the link.
(Other definitions for gathered that I've seen before include "Gleaned" , "Drew" , "assumed" , "Brought together in one place" , "Collected or assembled together" .)
