Expressing "not… but…" with "er shi"

Sometimes you want to explain that an object, concept, or event isn't one thing, but in fact a different thing. This is the perfect structure to convey that in Chinese.

Structure

"不是⋯⋯， (而)是⋯⋯" (bùshì..., (ér)shì...) is used to clarify something about a certain noun. What's being clarified can be noun phrases or verb phrases.

Subj. + 不是 + Noun 1 ， (而)是 + Noun 2

or 

Subj. + 不是 + [Verb Phrase 1] ， (而)是 + [Verb Phrase 2]

An easy way to remember this pattern is that it roughly corresponds to the English, "Something is not X, it's Y."

Examples

• 那 不是 一 个 困难，是 一 个 机会。That isn't a difficulty, it's an opportunity.
• 他 不是 中国人，是 美国人。He isn't Chinese, he's American.
• 这 个 大楼 不是 公寓，是 办公楼。This building isn't an apartment building, it's an office building.
