A snooker rest? (5)
I believe the answer is:
break
This could be a double definition.
'a snooker' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
I also know that 'snooker' relates to this answer.
'rest?' is the second definition.
(rest is a kind of break)
Can you help me to learn more?
(Other definitions for break that I've seen before include "Shatter; respite" , "Shatter; interval" , "Holiday; snap" , "interval between lessons" , "Time off working" .)
