Shock for a Scandinavian climber (5)

I believe the answer is:

appal

I'm a little stuck... Click here to teach me more about this clue!

'shock' is the definition.
(I know that shock is a more specific form of appal)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for appal that I've seen before include "expressed dismay" , "Cause to be unpleasantly surprised" , "Petrify" , "Put at rest (suspicion)" , "Greatly horrify" .)

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