1. 无价的；极贵重的；极为昂贵的
If you say that something is priceless, you are emphasizing that it is worth a very large amount of money.
2. 宝贵的；极其有用的
If you say that something is priceless, you approve of it because it is extremely useful.
Be careful not to confuse the words
priceless,
invaluable and
worthless. Something which is
priceless is so precious that it is difficult to give it a value.
…priceless masterpieces by Canova and Bernini. Something which is
invaluable is very useful indeed.
It has a spelling checker, which is invaluable if you are dyslexic. In contrast, something that is
worthless is of very little value.
I'm afraid your shares are now worthless.
注意不要混淆
priceless，invaluable 和 worthless。
priceless表示非常珍贵，因而难以计算其价值，如：
priceless masterpieces by Canova and Bernini（卡诺瓦和贝尔尼尼的无价杰作）。invaluable 表示非常有用，如：It has a spelling checker, which is invaluable if you are dyslexic（它带有一个拼写检查程序，对有诵读困难的人非常有用）。相反，worthless 表示没有什么价值，如：I'm afraid your shares are now worthless（恐怕你的股票现在一文不值了）。
