Record of work on board, by say end of December (7)
I believe the answer is:
dossier
'record' is the definition.
(I know that dossier is a type of written record)
'of work on board by say end of december' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is located in the answer.
'board' could be 'ss' (I've seen this in other clues) and 'ss' is found in the answer.
'end' could be 'die' and 'die' is found in the leftover letters.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dossier that I've seen before include "File of documents" , "Set of documents about person" , "Papers containing detailed information about someone" , "Report" , "Papers containing detailed information about a particular person" .)
