At heart Eleanor thinks: 'Significant point' (5)

I believe the answer is:

north

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

'point' is the definition.
(north is a kind of point)

'at heart eleanor thinks significant' is the wordplay.
'NORTH' is hidden in amongst the letters.
But, I am uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for north that I've seen before include "Thorn (anag.)" , "Direction that's usually "up" on a map" , "A 24 [STAR]" , "One looking for contract" , "who is opposed to East-West partnership?" .)

I've seen this clue in The Telegraph.
