Messaging you an item I ordered for details (8)
I believe the answer is:
minutiae
'details' is the definition.
(minutia is a kind of detail)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for minutiae that I've seen before include "Precise details" , "Trivia, very small details" , "Tiny or trivial details" , "trifles" , "Detailed particulars" .)
