elaborate

I'm a little stuck... Click here to teach me more about this clue!

'intricately worked out' is the definition.
I can't tell whether this defines the answer.

'being unusually able make a speech' is the wordplay.
'being unusually' is an anagram indicator.
'make a speech' becomes 'orate' (I've seen this in another clue).
'able' anagrammed gives 'elab'.
'elab'+'orate'='ELABORATE'

'that's' is the link.

Can you help me to learn more?

(Other definitions for elaborate that I've seen before include "Very ornate or complex" , "Complicate" , "Describe in detail, being complicated" , "Give more details" , "Complicated - complex" .)

I've seen this clue in The Irish Independent.
