Functions

Dōu 都 expresses ‘inclusiveness

Dōu 都 indicates that all items of the subject or object have something in common—do the same action or have the same quality. This shared characteristic is expressed by the predicate, a verb, or an adjective. It can be translated as “both” if there are two subjects or objects. If there are more than two, we translate it as ‘all’.

孩子们都爱唱歌。
孩子們都愛唱歌。

Zhè liǎng běn shū dōu hěn guì.
