Crossword Genius

Severe at the back (5)

Ross

I believe the answer is:

stern

I believe this clue is a double definition.

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

'the back' is the second definition.
(stern means the back of a boat)

'at' acts as a link.

(Other definitions for stern that I've seen before include "End part" , "Severe; grimly serious" , "Rigid" , "Grimly serious; back" , "Strict, austere" .)

I've seen this clue in The Mirror.
