Dangerous plant forming two shapes (9)
I believe the answer is:
sweatshop
'dangerous plant' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'forming two shapes' is the wordplay.
'forming' indicates an anagram.
'two'+'shapes'='twoshapes'
'twoshapes' is an anagram of 'SWEATSHOP'.
Can you help me to learn more?
(Other definitions for sweatshop that I've seen before include "Place for wretched workers" , "Place employing exploited workers" , "Factory (derog.)" , "where work is hard" , "Factory using underpaid labour" .)
