Truants are out at the eating place (10)
I believe the answer is:
restaurant
'the eating place' is the definition.
(I've seen this before)
'truants are out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'truants'+'are'='truantsare'
'truantsare' is an anagram of 'RESTAURANT'.
'at' acts as a link.
(Other definitions for restaurant that I've seen before include "Eatery" , "Eating place" , "table here?" .)
