Preliminary speech in favour of record, say (8)
I believe the answer is:
prologue
This clue could be a double definition.
'preliminary' is the first definition.
(thesaurus)
'speech in favour of record say' is the second definition.
'prologue' can be an answer for 'speech' (I have seen 'Introductory speech ' mean 'prologue' so perhaps 'speech' could also mean 'prologue'). I'm unsure of the 'in favour of record say' bit.
Can you help me to learn more?
(Other definitions for prologue that I've seen before include "Dramatic preface" , "opening speech" , "Introductory passage" , "Preface to a literary work" , "Start to play" .)
