Duck swimmer secretly shows off (7)
I believe the answer is:
immerse
'duck swimmer secretly shows off' is the definition.
I can't tell whether this defines the answer.
'duck swimmer secretly shows' is the wordplay.
'shows' says the answer is hidden in the clue.
'IMMERSE' is hidden in the letters of 'duck swimmer secretly'.
Can you help me to learn more?
(Other definitions for immerse that I've seen before include "Engage deeply" , "Baptise" , "Plunge deep into liquid" , "Cover with water, dip into" , "Dip totally into liquid" .)
