Graduate has true broadcast to get ready (6)
I believe the answer is:
mature
'ready' is the definition.
(thesaurus)
'graduate has true broadcast' is the wordplay.
'graduate' becomes 'ma' (abbreviation for Master of Arts).
'has' says to put letters next to each other.
'broadcast' indicates anagramming the letters.
'true' with letters rearranged gives 'ture'.
'ma'+'ture'='MATURE'
'to get' is the link.
(Other definitions for mature that I've seen before include "due to be paid" , "Fully grown and adult" , "reach the end of term" , "Ripe or fully grown" , "Fully grown and developed (6)" .)
