Latin lover

I came downstairs late this afternoon and she was sitting at the table. I did a double take. Yes, she WAS sitting at the table, but there was no food involved. Instead she was writing in a book.

I stared at her lap. She had those black velvet trousers on. They are really cosy.

Well, come on then, she said, patting her lap. Come and sit up here and help me with this Latin homework.

She didn't have to ask twice. Up I jumped and started pawing away. Nice.

Now then, she said. Translate each word and state what is the subject, what is the object, and what is the genitive.

Tee hee, I sniggered. She said genitive.
