A highly commendable speech (6)
I believe the answer is:
eulogy
'speech' is the definition.
(speech at a funeral)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for eulogy that I've seen before include "Speech highly praising someone" , "Accolade" , "Funeral oration" , "Expression of praise for someone recently dead" , "Formal expression of praise" .)
