Put one out of school schedule (9)
I believe the answer is:
translate
'put' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
'one out of school schedule' is the wordplay.
'one out of school' becomes 'tran' (I am not sure about this - if you are sure you should believe this answer much more).
'schedule' becomes 'slate' (as in a film slated for release).
'tran'+'slate'='TRANSLATE'
Can you help me to learn more?
(Other definitions for translate that I've seen before include "Explain" , "Express in a different language" , "shift" , "make comprehensible" , "Change the language of (a text)" .)
