Noble time (6)
I believe the answer is:
august
This clue might be a double definition.
'noble' is the first definition.
(similar in meaning)
'time' is the second definition.
The definition and answer can be both related to time as well as being singular nouns.
Perhaps there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for august that I've seen before include "Grand, lordly" , "Majestic or imposing, like month" , "comic entertainer for children" , "part of the year" , "A grand month?" .)
