Got back there to assemble in a group (8)
I believe the answer is:
together
'group' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'got back there to assemble' is the wordplay.
'back' says the letters should be written backwards.
'to assemble' indicates anagramming the letters.
'got' reversed gives 'tog'.
'there' anagrammed gives 'ether'.
'tog'+'ether'='TOGETHER'
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for together that I've seen before include "in league" , "at the same time" , "stable" , "Well-balanced" , "Got there (anag.)" .)
