Cornice excited English tour guide (8)
I believe the answer is:
cicerone
'tour guide' is the definition.
(I've seen this in another clue)
'cornice excited english' is the wordplay.
'excited' indicates anagramming the letters.
'english' becomes 'E' (abbreviation).
'cornice' is an anagram of 'ciceron'.
'ciceron'+'e'='CICERONE'
(Other definitions for cicerone that I've seen before include "who shows visitors round?" , "A guide supplied by rice cone, strangely" .)
