Stern breed? (4)
I believe the answer is:
rear
This clue is a double definition.
'stern' is the first definition.
(I know that stern can be written as rear)
'breed?' is the second definition.
(I've seen this in another clue)
(Other definitions for rear that I've seen before include "what you may bring up" , "Bring up and care for" , "Rare at the back" , "Raise - back" , "Back; bring up (young)" .)
