Make a union defer tea break (8)
I believe the answer is:
federate
'make a union defer tea break' is the definition.
I can't judge whether this defines the answer.
'defer tea break' is the wordplay.
'break' is an anagram indicator.
'defer'+'tea'='defertea'
'defertea' with letters rearranged gives 'FEDERATE'.
Can you help me to learn more?
(Other definitions for federate that I've seen before include "United" , "Join in a league" , "Form an alliance" .)
