Love extremely avid speech (9)
I believe the answer is:
Here is my best explanation:
'love' is the definition.
(I've seen this before)
'extremely avid speech' is the subsidiary indication.
'extremely' suggests removing the centre.
'speech' becomes 'oration' (oration is a kind of speech**).
'avid' with its middle removed is 'ad'.
(Other definitions for adoration that I've seen before include "Love", "Deep love and respect", "Veneration", "Not a radio (anag.)", "Hero-worship", "Great affection", "Worship, veneration" and "Feeling of profound love".)
