"Convenient" is a word that can be used to describe something that is easy to use or access, and is therefore helpful or useful. It is derived from the Latin word "convenire," which means "to come together."
Here are some examples of how "convenient" can be used in a sentence:
It's convenient that the store is open late, so I can do my shopping after work. (这家商店开晚了很方便，所以我可以下班后去购物。)
The hotel has a convenient location, close to many restaurants and attractions. (这家酒店位置方便，靠近许多餐馆和景点。)
It would be more convenient if you could send the documents electronically, rather than by mail. (如果你能电子邮件发送文件就更方便了，而不是邮寄。)
