spoof

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

'deception' is the definition.
(thesaurus)

'start speculating for wealth albeit by' is the wordplay.
I cannot quite see how this works, but
'by' could be 'of' and 'of' is present in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
