Suffix with east or west (3)

I believe the answer is:

ern

'suffix with east or west' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for ern that I've seen before include "Eric Morecambe's partner" , "Little Ernest" .)

I've seen this clue in The New York Times, the L.A. Times Daily and the King Feature Syndicate.
