"Orange" is the Engpsh translation for "橙子" (chéngzi) in Mandarin Chinese. The word "orange" comes from the Old French word "orenge" which in turn comes from the Arabic word "nāranj" which refers to the fruit.

Here are some example sentences in Engpsh and their translations in Chinese:

"I pke to eat oranges." ("我喜欢吃橙子。" wǒ xǐhuan chī chéngzi.)

"He bought a bag of oranges at the market." ("他在市场上买了一袋橙子。" tā zài shìchǎng shàng mǎi le yī dài chéngzi.)
