The break a snooker player may need (4)
I believe the answer is:
rest
'the break' is the definition.
(a rest is taking a break)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rest that I've seen before include "Remain" , "Relax with residue" , "'''God ... ye, merry gentlemen'' (carol) (4)'" , "Pole in Crucible?" , "Remainder; relax" .)
