HSK 3

yóu

由 (by, from, due to)

Explanation

由 (yóu) is a preposition (a word placed before a noun to indicate a relationship: from, by, through...), used to state the starting point or place of origin of an action.

Structure

由 (yóu) + place/starting point + verb. For example 由北京机场出发 (yóu Běijīng jīchǎng chūfā) = depart from Beijing Airport.

When to use

When you want to clearly indicate the point of departure or the route taken; it is formal in style, often seen in announcements and instructions (由南门进入 = enter through the South Gate).

Distinguish

由 and 从 (cóng) both mean "from", but 由 is more formal and also implies "through, by"; in everyday conversation people tend to use 从 more.

Common mistakes

Placing 由 in the wrong position (it must come before the place, before the verb); overusing 由 in everyday speech sounds stiff — 从 should be used instead.
