The last letter of an answer is the first letter of next answer.
8 Add nomenclature to dish for clarification 9 letters beginning with N ending with E
15 Angrily hit, rob and mug (no Italian) hat 7 letters beginning with H
16 Chocolate is out of this worls 6 letters ending with M
That is hoping my answers are correct for other answers.
