The man's doughnut-shaped and of a certain age (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
historic
'and of a certain age' is the definition.
I can't tell whether this defines the answer.
'the man's doughnut-shaped' is the wordplay.
'the man's' becomes 'his' (belonging to a man).
'doughnut-shaped' becomes 'toric' (I've seen this before).
'his'+'toric'='HISTORIC'
Can you help me to learn more?
(Other definitions for historic that I've seen before include "Pertaining to what is important in the past" , "sort of present" , "Significant" , "Momentous, noteworthy" , "Memorable" .)
