Now I'm stuck on the last one!
22 down: Another name for dentine especially in animals (5) A_O_Y
Now, I'm sure the answer should be Ivory, yet I've got an 'A' to start with (this comes from the last letter in CasanovA)
Help!
Thanks in advance

It is ivory, 21a is macaroni

Thank you Ulysses100 you've saved my bacon again!

If the answer is macaroni how did you arrive at Casanova?

[bibblebub]

it's next to casava in the dictionary

[Lie-in King]

In which dictionary, b'bub? :-)

[bibblebub]
