Strait separating the Isle of Wight from the mainland (6)

Ross

I believe the answer is:

solent

(Other definitions for solent that I've seen before include "Lets on to be an English waterway" , "Strait off Portsmouth" , "Water to north of IOW" , "Channel N. of IOW" , "sound" .)

I've seen this clue in The Times.
