Items of business information original person almost absorbs (6)
I believe the answer is:
agenda
'items of business' is the definition.
(I've seen this before)
'information original person almost absorbs' is the wordplay.
I cannot really see how this works, but
'information' could be 'gen' (gen can informally mean information) and 'gen' is found within the answer.
'person' could be 'da' (D.A. is an example) and 'da' is present in the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for agenda that I've seen before include "Plan for meeting" , "Table of business" , "Schedule, order of business" , "List of items of business for committee" , "Items of business for committee meeting" .)
