See about getting in the water (5)
I believe the answer is:
seine
'water' is the definition.
(Seine is an example)
'see about getting' is the wordplay.
'about' is an insertion indicator.
'getting' becomes 'in' (I can't justify this - if you can you should give a lot more credence to this answer).
'see' going around 'in' is 'SEINE'.
'in the' is the link.
Can you help me to learn more?
(Other definitions for seine that I've seen before include "Second longest river in France" , "French river -- type of fishing net" , "Paris river" , "Parisian river" , "Paris's river" .)
