a child of a person's aunt or uncle, or, more generally, a distant (= not close) relation

My brother's wife and I both had babies around the same time, so the cousins are very close in age. 我嫂子和我差不多同时生了孩子，因此这对表兄妹年纪相仿。

Many of our distant cousins, whom we hadn't seen for years, came to my sister's wedding. 我们家许多多年未见的远房亲戚赶来参加姐姐的婚礼。

We Americans owe a great deal to our European cousins. 我们美国人得到欧洲兄弟的许多帮助。
