Urge pool model to put this in a book at the start (8)
I believe the answer is:
prologue
'put this in a book at the start' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'urge pool model' is the wordplay.
'model' is an anagram indicator.
'urge'+'pool'='urgepool'
'urgepool' is an anagram of 'PROLOGUE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for prologue that I've seen before include "Foreword" , "Dramatic preface" , "Introductory speech" , "Introductory piece" , "Introductory passage" .)
