Ready for homework to read out (8)
I believe the answer is:
prepared
'ready' is the definition.
(similar in meaning)
'homework to read out' is the wordplay.
'homework' becomes 'prep' (synonyms).
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'read' anagrammed gives 'ared'.
'prep'+'ared'='PREPARED'
'for' acts as a link.
(Other definitions for prepared that I've seen before include "edited" , "All set" , "Waiting" , "Ready for action" , "Made or got ready" .)
