只vs.仅仅vs.唯一

[Zhende ma?]

只vs.仅仅vs.唯一

Can anyone give me some good usage tips for these? I know that 只 means "only" and 仅仅 is more like "merely" but where is 唯一 usually used?

只 is the adverb form of "only"， e.g. 我只吃巧克力。

唯一 is the adjective form of "only," e.g. 我唯一的问题就是不懂怎么用这词。

[TaijiMantis]

只 和 仅仅 有时候可以互换，比如

只来了一个人/仅仅来了一个人

仅仅更书面化一点，口语里面很少。

唯一可以做名词，e.g.

你就是我的唯一。（u a my last）

可以作形容词，

如前面“唯一的问题”

但是不能作副词，就是不能修饰动作。

只来了一个人，不能说 唯一来了一个人。
