Lure duck briefly into view (6)
I believe the answer is:
seduce
'lure' is the definition.
(I know that seduce is a more specific form of lure)
'duck briefly into view' is the wordplay.
'briefly' means to remove the last letter.
'into' is an insertion indicator.
'view' becomes 'see' (synonyms).
'duck' with its final letter removed is 'duc'.
'duc' put into 'see' is 'SEDUCE'.
(Other definitions for seduce that I've seen before include "Win over" , "Persuade to be false" , "Lead astray, tempt" , "Persuade (someone) to act inadvisably" , "Beguile" .)
