Hired easel out on the day (6)
I believe the answer is:
leased
'hired' is the definition.
('lease' can be a synonym of 'hire')
'easel out on the day' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'on' means one lot of letters go next to another.
'the day' becomes 'd' (**).
'easel' anagrammed gives 'lease'.
'lease'+'d'='LEASED'
(Other definitions for leased that I've seen before include "Rented" , "Let for money" .)
