Played up rage in the spring of 1968 (6)
I believe the answer is:
prague
'the spring of 1968' is the definition.
I can't judge whether this defines the answer.
'played up rage' is the wordplay.
'played' indicates anagramming the letters.
'up'+'rage'='uprage'
'uprage' with letters rearranged gives 'PRAGUE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for prague that I've seen before include "Gear up for this European city" , "Czech Republic's capital" , "European capital" , "Rather quiet" , "Capital city of Czech Republic" .)
