Reverence for commercial speech (9)
I believe the answer is:
adoration
'reverence' is the definition.
(thesaurus)
'commercial speech' is the wordplay.
'commercial' becomes 'ad' (abbreviation for advertisement).
'speech' becomes 'oration' (oration is a kind of speech).
'ad'+'oration'='ADORATION'
'for' is the link.
(Other definitions for adoration that I've seen before include "praise" , "Not a radio (anag.)" , "high esteem" , "holding someone up a lot" , "Honour" .)
