Decade with restrictions for every day of the week (9)
I believe the answer is:
seventies
'decade' is the definition.
(I know that Seventies is a type of decade)
'restrictions for every day of the week' is the wordplay.
I cannot really understand how this works, but
'restrictions' could be 'ties' and 'ties' is found within the answer.
'day' could be 'eve' (eve is a kind of day) and 'eve' is found in the answer.
This explanation may well be incorrect...
'with' is the link.
Can you help me to learn more?
(Other definitions for seventies that I've seen before include "Decade of the Arms crisis, Vietnam and All Kinds of Everything" , "retirement years?" .)
