Full-bodied tirade about beak rising (8)
I believe the answer is:
resonant
'full' is the definition.
(thesaurus)
'bodied tirade about beak rising' is the wordplay.
'bodied tirade' becomes 'rant' (I've seen this before. I am not sure about the 'bodied' bit.**).
'about' is an insertion indicator.
'beak' becomes 'nose' (I've seen this before).
'rising' says the letters should be written in reverse (going up in a down clue).
'nose' written backwards gives 'eson'.
'rant' enclosing 'eson' is 'RESONANT'.
Can you help me to learn more?
(Other definitions for resonant that I've seen before include "Sonorous, full and rich in sound" , "(Of sound) deep and ringing" , "Re-echoing" , "Deep, clear and continuing to sound or reverberate" , "Like" .)
