Equal, even, equivalent, and tantamount all mean 'the same', but tone differs: equal is plain and common; even often means level, as in a tied score; equivalent is formal, comparing different categories; tantamount is formal, only in 'tantamount to', for something serious.

这四个词在“相等、相当”这个意义上很接近，但语气和用法不同：equal 最普通中性，even 多用于比分或对比双方变得持平，equivalent 较正式，常用于比较不同类别的事物，tantamount 最正式，只用于“tantamount to”这个固定搭配，且多指负面或严重的事情。这里不比较 even 的“平坦的”和“偶数的”义项。
