Be warm hearted and put up with things (4)

I believe the answer is:

bear

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

'put up with things' is the definition.
I can't tell whether this defines the answer.

'be warm hearted' is the wordplay.
'hearted' indicates the central letters.
The middle of 'warm' is 'ar'.
'be'+'ar'='BEAR'

'and' is the link.

Can you help me to learn more?

(Other definitions for bear that I've seen before include "Relating to charged particles" , "Support; wild animal" , "See 13 across" , "Carry, convey" , "Tolerate; animal" .)

I've seen this clue in the Evening Standard.
