Amazed by the speculator and the awful greed (9)
I believe the answer is:
staggered
'amazed' is the definition.
(I've seen this before)
'the speculator and the awful greed' is the wordplay.
'the speculator' becomes 'stag' (I've seen this before).
'and' says to put letters next to each other.
'the awful' indicates an anagram.
'greed' anagrammed gives 'gered'.
'stag'+'gered'='STAGGERED'
'by' is the link.
(Other definitions for staggered that I've seen before include "Deeply shocked or walked unsteadily as if about to fall" , "Moved unsteadily, being deeply shocked" , "Gobsmacked" , "Arranged to take place at intervals" , "Amazed" .)
