I believe the answer is:

sea

I'm a little stuck... Click here to teach me more about this clue!

'water' is the definition.
(the sea is water)

I don't understand how the remainder of the clue works.

(Other definitions for sea that I've seen before include "The Med, e.g." , "Lesser ocean" , "Expanse of salt water" , "The main" , "Eg, Aral, Ross, Irish" .)

I've seen this clue in the Evening Standard.
