SST part (5)

Ross

I believe the answer is:

sonic

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

This is all the clue.

(Other definitions for sonic that I've seen before include "Relating to the speed of sound" , "Like mine, possibly" , "Boom of jet aircraft" , "Sort of boom" , "Employing sound" .)

I've seen this clue in the King Feature Syndicate and the LA Times.
