The times we're living to the full? (4,6)
I believe the answer is:
anno domini
'the times' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?
I cannot understand how the remainder of the clue works.
(Other definitions for anno domini that I've seen before include "AD in full" , "having a date, she may put it on" , "Advancing old age (informal)" , "In the year of our Lord" , "later days" .)
