Structure (结构 jiégòu)

Subject是Object

Meaning (意思 yìsi)

The verb 是 is used to affirm that thing A is thing B, equivalent to "is/are/am" in English.

Explanation (解释 jiěshì)

The verb 是 (shì) is the most basic way to say "A is B," used to introduce, confirm, or define. It links two nouns or noun phrases together.

The negative of 是 is 不是 (bú shì), meaning "is not."

Important note: do not use 是 before an adjective. To say "I am well," you say 我很好 (wǒ hěn hǎo), not 我是好. 是 is used only to connect two equivalent things (noun = noun), not to describe (noun + adjective).
