Modifier + 的 + Noun
The particle 的 connects a modifying phrase to a noun, similar to the possessive "'s" or "of" in English. It can express possession (我的书, "my book"), describe attributes (红色的车, "red car"), or link longer phrases to a noun. It is one of the most common structural particles in Chinese.

zhè shì wǒ māma de shǒujī.
This is my mom's phone.
