Equivocate as casual worker with zero extra money (9)
I believe the answer is:
Here is my best explanation:
'equivocate' is the definition.
'casual worker with zero extra money' is the wordplay.
'casual worker' becomes 'temp' (I've seen this before).
'with' means one lot of letters go next to another.
'zero' becomes 'o'.
'extra money' becomes 'rise'.
'as' is the link.
(Other definitions for temporise that I've seen before include "Delay", "fail to decide", "Hedge", "Emptier so as to avoid giving a definite answer" and "Put off".)
