Too far gone to be historic? (4)
I believe the answer is:
past
This clue might be a double definition.
'too far gone' is the first definition.
'past' can be an answer for 'gone' ('past' can be similar in meaning to 'gone'). I am unsure of the 'too far' bit.
'historic?' is the second definition.
('past' can be similar in meaning to 'historic')
'to be' is the link.
Can you help me to learn more?
(Other definitions for past that I've seen before include "over and done with" , "Beyond" , "Gone by in time" , "Bygone" , "The time that has elapsed" .)
