States extract freeloader (5)
I believe the answer is:
leech
This clue could be a double definition.
'states extract' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'freeloader' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for leech that I've seen before include "Annelid worm, used in medicine of old" , "Blood-sucking worm or parasitic person" , "Old physician" , "Old medicinal sucker" , "Blood-sucking worm or parasitical person" .)
