I have encountered such a term, and I have no idea what it is. Could it be 'of'?
Norman genitive, or French genitive, is another term for analytic genitive. The following phrases use the Norman genitive.
- the future of mankind
- the roof of your house
- the leaves of those trees
The following phrases use the Saxon genitive, or synthetic genitive.
- Michael's sister
- Joanna's boyfriend
- the cat's leg
The analytic genitive, also known as the French or Norman genitive, is the genitive in "of" form, like "The question of Lukas", "The answer of Phoenix", "The house of John", "the doors of the car". The other form is the synthetic genitive, also known as the Saxon genitive, which is the possessive with the apostrophe, like "Lukas' question", "Phoenix's answer", "John's house", "The car's doors"
In Modern English, both constructions are frequently encountered, as pointed out in the other answers. There is, however, a decided preference for use of the Saxon genitive with human or animate possessors,
- *the house of Bill ~ Bill's house
- *the leg of Fido ~ Fido's leg
but the Norman genitive with inanimate possessors:
- *the table's foot ~ the foot of the table
- *the day's middle ~ the middle of the day
As usual, Language makes opportunistic use of an accidental form distinction to mark a functional distinction.
