SOS! (4)

Ross

I believe the answer is:

help

'sos' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for help that I've seen before include "record by the Beatles" , "Contribute to the success of" , "one by the Beatles" , "Be of service" , "Serve" .)

I've seen this clue in The Guardian and The Star Tribune.
