Calibrate rule about nearly everything (7)
I believe the answer is:
realign
'calibrate' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'rule about nearly everything' is the wordplay.
'rule' becomes 'reign' (synonyms).
'about' indicates putting letters inside.
'nearly' means to remove the last letter.
'everything' becomes 'all' (all things).
'all' with its last letter removed is 'al'.
'reign' enclosing 'al' is 'REALIGN'.
Can you help me to learn more?
(Other definitions for realign that I've seen before include "Change to a new position" , "Set straight" , "Arrange again" , "Again order" , "Group or divide on a new basis" .)
