A theologian with hesitation about death, as shown in final notes? (8)
I believe the answer is:
addendum
'as shown in final notes?' is the definition.
I can't tell whether this defines the answer.
'a theologian with hesitation about death' is the wordplay.
'theologian' becomes 'DD' (Doctor of Divinity degree).
'with' is a charade indicator (letters next to each other).
'hesitation' becomes 'um' (sound made when hesitating).
'about' means one lot of letters go next to another.
'death' becomes 'end' (synonyms).
'um' after 'end' is 'endum'.
'dd'+'endum' is 'ddendum'.
'a'+'ddendum'='ADDENDUM'
Can you help me to learn more?
(Other definitions for addendum that I've seen before include "Supplementary text tacked on to the end" , "something tacked on" , "Additional material at the back of a book" , "Additional item at the end of a book" , "Addition at end of book" .)
