Get rid of the things we doubt? (4,3)
I believe the answer is:
weed out
'get rid of' is the definition.
(weeding out is a kind of getting rid of)
'the things we doubt?' is the wordplay.
I cannot quite understand how this works, but
'we' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for weed out that I've seen before include "Remove unwanted elements" , "Identify and get rid of" , "Eliminate" .)
