'farewell words' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'extraordinary respect in a people's final' is the wordplay.
'extraordinary' indicates anagramming the letters.
'final' suggests the final letters.
The last letter of 'people' is 'e'.
'respect'+'in'+'a'='respectina'
'respectina' anagrammed gives 'restinpeac'.
'restinpeac'+'e'='REST IN PEACE'
