Saxon Genitive vs. Norman Genitive

As you can see, the apostrophe is quite often misused, so try to learn to use it correctly.

Up to now, we have talked about the Saxon Genitive or the Genitive Case. They are not the same. The Genitive Case is used to express far more relationships than that of possession. For example, the phrase a glass of milk is genitive, but it is not Saxon Genitive, since the milk does not possess the glass. The Saxon Genitive derives its name from the Anglo-Saxon, since in Old English, the genitive was formed by adding -es to the noun. As we now know, in modern English 's is added.

Nevertheless, it is not the only way we have to refer to possessions or relationships. We also have, as you guessed at the beginning of the topic, the well-known of-construction or Norman Genitive, and this is what we will study in the last section of the topic.
