初めてです, is '初めて' an adverb?


I saw following quotes:

[code]

    アメリカは初めてです。 
    This is my first time to America. 
    
[/code]

I've learned about `<n.> は <n.|adj.> です`. Checking at several dictionaries,
'初めて' is an adverb. Is it OK to use an adverb in `<n.> は <adv.> です`?




No, you cannot attach です to an adverb. But 初めて is **both** an adverb and no-
adjective. (A no-adjective is a special type of noun that is semantically
similar to an English adjective. See [this
question](https://japanese.stackexchange.com/q/2770/5010).) You can confirm
this fact in [jisho.org's
entry](https://jisho.org/search/%E5%88%9D%E3%82%81%E3%81%A6). For example, you
can say 初めてのアメリカ, which means "(my) first (trip to) America".

(Similar things happen all the time also in English; _fast_ as in "this train
is fast" is an adjective, but _fast_ as in "this train runs fast" is an
adverb.)
