King emerging from bitter exile (3)

I believe the answer is:

rex

'king' is the definition.
('king' in Latin)

'emerging from bitter exile' is the wordplay.
'emerging from' indicates the answer is hidden within the clue.
'REX' is hidden in the letters of 'bitter exile'.

(Other definitions for rex that I've seen before include "See 6" , "King (L.)" , "Part of official title of a king" , "King's title" , "King (Latin); cat breed" .)

I've seen this clue in The Globe and Mail.
