Makes someone take notice? (7)
I believe the answer is:
resigns
'makes' is the definition.
The definition and answer can be both related to thinking as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'someone take notice?' is the wordplay.
'someone' becomes 'res' (I am not sure about this - if you are sure you should believe this answer much more).
'take' means one lot of letters goes inside another.
'notice?' becomes 'sign' (notice is a kind of sign).
'res' placed around 'sign' is 'RESIGNS'.
Can you help me to learn more?
(Other definitions for resigns that I've seen before include "Leaves job voluntarily" , "does the honourable thing" , "Gives up (a post)" , "abdicates" .)
