motives

'these reasons' is the definition.
(I've seen this in another clue)

'stirs it back in' is the wordplay.
'stirs' becomes 'moves' (I can't justify this - if you can you should believe this answer much more).
'back' is a reversal indicator.
'in' indicates putting letters inside.
'it' in reverse letter order is 'ti'.
'moves' enclosing 'ti' is 'MOTIVES'.

'for' acts as a link.

Can you help me to learn more?

(Other definitions for motives that I've seen before include "inducements" , "They're why" , "Reasons for action" .)
