A good chance for a rest (5)
I believe the answer is:
break
This clue could be a double definition.
'a good chance' is the first definition.
'break' can be an answer for 'chance' (thesaurus). I'm not sure about the 'a good' bit.
'for a rest' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for break that I've seen before include "Fracture; holiday" , "Baker (anag.)" , "Interrupt - rest period" , "Holiday; snap" , "interval between lessons" .)
