Point ride out to duck (5)
I believe the answer is:
eider
'to duck' is the definition.
(eider is a type of duck)
'point ride out' is the wordplay.
'point' becomes 'e' (compass point).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'ride' is an anagram of 'ider'.
'e'+'ider'='EIDER'
(Other definitions for eider that I've seen before include "Duck with soft feathers" , "Duck from which down is obtained" , "Reed I turn into a duck" , "Duck noted for down" , "Breed of duck" .)
