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

'fiery feeling' is the definition.
'ardour' can be an answer for 'feeling' (ardour is a kind of feeling). I'm not sure about the 'fiery' bit.

'hatred periodically shared by us' is the wordplay.
'periodically' indicates alternate letters (letters must be selected 'every so often').
'shared by us' becomes 'our' (I've seen this in another clue).
The alternating letters of 'hatred' are 'ard'.
'ard'+'our'='ARDOUR'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for ardour that I've seen before include "Passionate warmth" , "Passionate zeal" , "Fervour or passion" , "causing some heat" , "Great warmth of feeling or love" .)
