Show auto initially entering, not fully charged (8)
I believe the answer is:
indicate
'show' is the definition.
(I know that show can be written as indicate)
'auto initially entering not fully charged' is the wordplay.
'auto initially' becomes 'a' (I can't justify this - if you can you should give a lot more credence to this answer).
'entering' indicates putting letters inside.
'not fully' means to remove the last letter.
'charged' becomes 'indicted' (to indict is to charge with a crime).
'indicted' with its final letter taken away is 'indicte'.
'a' put within 'indicte' is 'INDICATE'.
(Other definitions for indicate that I've seen before include "Point out, make known" , "Make a signal" , "Point out, suggest" , "Point out or give some notion of" , "Point, show, signal" .)
