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

'rugged scot' is the definition.
The definition suggests a singular noun which matches the answer.

I don't understand the remainder of the clue.

(Other definitions for craig that I've seen before include "Fellow" , "Scottish boy" , "Daniel --, actor" .)

I've seen this clue in the Evening Standard.
