If going north, live somewhere warm (8)

I believe the answer is:

fireside

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

'somewhere warm' is the definition.
I can't judge whether this defines the answer.

'if going north live' is the wordplay.
'going north' is a reversal indicator.
'live' becomes 'reside' (residing is a kind of living).
'if' written backwards gives 'fi'.
'fi'+'reside'='FIRESIDE'

Can you help me to learn more?

(Other definitions for fireside that I've seen before include "Comfy place for chair" , "Domestic situation" , "Inglenook" , "Warm domestic area" , "One warmed by this" .)
