Have something in mind (7)
I believe the answer is:
imagine
'mind' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'have something in' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
The remaining letters 'image' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for imagine that I've seen before include "Devise" , "Number one" , "Conjure up in mind,fancy" , "Assume" , "Suppose; think up" .)
