An advancing predator? (4,5)
I believe the answer is:
loan shark
'an advancing predator?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'advancing predator?' is the wordplay.
'advancing' becomes 'loan' (I am not sure about this - if you are sure you should believe this answer much more).
'predator?' becomes 'shark' (I've seen this before).
'loan'+'shark'='LOAN SHARK'
Can you help me to learn more?
(Other definitions for loan shark that I've seen before include "Money lender" , "Usurer" , "One lends money at excessive rates of interest" , "Unscrupulous moneylender (colloq.)" , "Financial dealer" .)
