July holiday in the US for the auditor’s out (5)
I believe the answer is:
forth
'out' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for forth that I've seen before include "Onward direction" , "Edinburgh's river" , "(Go) away" , "Out and away -- UK shipping forecast area" , "Onward; the Firth of - -" .)
