Arrive and greet the assembly (3,5)
I believe the answer is:
get there
'arrive' is the definition.
(thesaurus)
'greet the assembly' is the wordplay.
'assembly' is an anagram indicator.
'greet'+'the'='greetthe'
'greetthe' anagrammed gives 'GET THERE'.
'and' acts as a link.
(Other definitions for get there that I've seen before include "Order to move away" , "understand what is meant" , "succeed" , "Achieve one's object" .)
