Rents out flyers (5)
I believe the answer is:
terns
'flyers' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.
'rents out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'rents' with letters rearranged gives 'TERNS'.
Can you help me to learn more?
(Other definitions for terns that I've seen before include "Sea bird with long forked tail" , "Sea birds with long forked tails" , "Aquatic birds" , "Seabirds" , "Rents out these birds" .)
