Complicated way to supply details (9)
I believe the answer is:
elaborate
'complicated' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for elaborate that I've seen before include "Work out or describe in detail" , "flesh out?" , "Detailed, complicated" , "Describe in detail, being complicated" , "involved" .)
