A pest we get wicked with (6)
I believe the answer is:
weevil
'a pest' is the definition.
(I've seen this before)
'we get wicked with' is the wordplay.
I cannot quite understand how this works, but
'we' is found in the answer.
'wicked' could be 'evil' (similar in meaning) and 'evil' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for weevil that I've seen before include "Small beetle, pest of crops" , "Destructive beetle" , "Small kind of 15 down" , "it goes against the grain!" , "Evil we find strangely in a beetle" .)
