MANDARIN SENTENCE PATTERN
Possession with 的
Connect an owner or description to a noun.
Owner + 的 (de) + noun
的 follows an owner or modifier and connects it to the noun. The owner comes first, unlike the English phrase the book of my friend.
的 can be omitted in some close relationships, such as 我妈妈, but keeping it initially is often a useful beginner pattern.
Examples
这是我的书。
This is my book.
你的朋友在哪儿?
Where is your friend?
她的名字很好听。
Her name sounds nice.
Keep in mind
的 is usually neutral tone in this pattern. Do not confuse it with the similar-sounding 地 and 得.
