Afterwards take a novice to one side (7)

I believe the answer is:

lateral

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

'to one side' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for lateral that I've seen before include "Relating to the side" , "Way of thinking" , "Sideways, like creative thinking" , "One type of thinking" , "Of, at or towards the sides (7)" .)

I've seen this clue in The Mirror.
