Prisoner's muddled memo that's clear for Spooner? (8)
I believe the answer is:
consomme
'clear for spooner?' is the definition.
The definition suggests a singular noun which matches the answer.
'prisoner's muddled memo' is the wordplay.
'prisoner's' becomes 'con's' (abbreviation for 'convict').
'muddled' is an anagram indicator.
'memo' anagrammed gives 'omme'.
'cons'+'omme'='CONSOMME'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for consomme that I've seen before include "starter course" , "Thin, clear soup" , "Liquid food" , "Clear French meat soup" , "Clear soup made with concentrated stock" .)
