Distinguished period (6)
I believe the answer is:
august
This clue is a double definition.
'distinguished' is the first definition.
(I've seen this before)
'period' is the second definition.
(August is an example)
(Other definitions for august that I've seen before include "clown in circus" , ". . . . . . is a Wicked Month (Edna O'Brien)" , "Respected and impressive in the month" , "Month befitting a lord" , "Dignified - month" .)
