Obtain inner satisfaction (3)
I believe the answer is:
eat
'obtain' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eat that I've seen before include "Make food disappear" , "Take food" , "tolerate in diet" , "Have 23d [MEAL]" , "Corrode" .)
