More damn trouble about a batch of notes! (9)
I believe the answer is:
memoranda
'batch of notes' is the definition.
'memoranda' can be an answer for 'notes' (more than one memorandum). I'm not sure about the 'batch of' bit.
'more damn trouble about a' is the wordplay.
'trouble' is an anagram indicator.
'about' indicates putting letters inside.
'more'+'damn'='moredamn'
'moredamn' with letters rearranged gives 'memornda'.
'memornda' enclosing 'a' is 'MEMORANDA'.
Can you help me to learn more?
(Other definitions for memoranda that I've seen before include "Communications" , "official minutes" , "Notes recorded for future use" , "Records" , "Written messages or notes" .)
