Increase (7)

Ross

'increase' is the definition.
(swelling is a kind of increasing)

This is all the clue.

(Other definitions for swell that I've seen before include "Burgeon" , "Heave of sea; expand" , "Heave of the sea's surface" , "mushroom" , "blowing top" .)

I've seen this clue in The Telegraph, The New York Times, the King Feature Syndicate, the Evening Standard and The Mirror.
