Worst and best hiatus in race? (3,4)
I believe the answer is:
pit stop
'hiatus in race?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'worst and best' is the wordplay.
'worst' becomes 'pits' (I've seen this in another clue).
'and' is a charade indicator (letters next to each other).
'best' becomes 'top' (top can mean the very best).
'pits'+'top'='PIT STOP'
Can you help me to learn more?
(Other definitions for pit stop that I've seen before include "for rest of travellers" , "brief service" , "period of service?" , "part of the race" , "place where car can be serviced - with 31a" .)
