Tell us more about how intricate it is? (9)

I believe the answer is:
elaborate
'tell' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.

I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for elaborate that I've seen before include "with added detail" , "Complicated or fancy" , "Add details to clarify meaning" , "With many parts or details, maybe a pattern" , "Extravagant" .)
