Accustom debutante to jumping out of bed (6)
I believe the answer is:
attune
'accustom' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for attune that I've seen before include "Harmonise or adapt, say mind to idea" , "Orient" , "Get used to" , "Adjust (to a situation)" , "Harmonise or adapt to idea or music" .)
