Report of a good innings, remarkable one with your bat (8)
I believe the answer is:
obituary
'report of a good innings' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'remarkable one with your bat' is the wordplay.
'remarkable' is an anagram indicator.
'one' becomes 'i' (Roman numeral).
'with' says to put letters next to each other.
'your'+'bat'='yourbat'
'i' after 'yourbat' is 'yourbati'.
'yourbati' anagrammed gives 'OBITUARY'.
Can you help me to learn more?
(Other definitions for obituary that I've seen before include "Newspaper article about person recently dead" , "Death notice with biographical account" , "Brief published biography of recently deceased person" , "Brief newspaper feature on death of prominent person" , "Short newspaper piece about deceased luminary" .)
