Make clear what is foreign to us? (9)
I believe the answer is:
interpret
'make' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.
Maybe you can see an association between them that I don't see?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for interpret that I've seen before include "Orally translate" , "Explain the meaning of - another language?" , "Explain the meaning of, perhaps a foreign language" , "Assign one's own meaning to" , "Construe" .)
