Skunk perhaps behind low-quality paper plant (7)
I believe the answer is:
ragweed
'plant' is the definition.
The answer is an example.
'skunk perhaps behind low-quality paper' is the wordplay.
'skunk perhaps' becomes 'weed' (synonyms. I am not sure about the 'perhaps' bit.).
'behind' means one lot of letters go next to another.
'low-quality paper' becomes 'rag' (I've seen this in another clue).
'weed' put after 'rag' is 'RAGWEED'.
Can you help me to learn more?
(Other definitions for ragweed that I've seen before include "Plant of daisy family" , "bloomer" , "Allergenic plant" , "Unwanted plant with yellow flowers" , "Threat to horses" .)
