Understanding あんなの見に行ったの


From the first episode of Death Note:

> マジで？ あんなの見に行ったの？

**Questions:**

  1. I know that "あんな" (labeled as a "pre-noun adjective" in my dictionary) means "that sort of thing". Grammatically, is this word just あん + な (where あん is a な-adjective, and the な is just being appended to it to allow it to modify a noun)?

  2. Is the の after あんな "nominalizing" あんな?

  3. Is 見に行った seen as a single word, or is it (見 + に) + 行った? If the latter, does adding に to verbs transform to the infinitive form? So for example does 見に mean "to see", in this context (so that the whole sentence means "You came **to see** that sort of thing"?




School-grammatically and according to デジタル大辞泉,
[あんな](https://dictionary.goo.ne.jp/word/%E3%81%82%E3%82%93%E3%81%AA/#jn-8836)
is na-adjective (形容動詞). From the entry (bold added):

> **あんな has two pre-noun forms あんな and あんなな. Usually あんな is used** , but
> before ので/のに, あんなな is used. E.g., 事態があんななので、どうすることもできない.

So rather than あん+な, it is あんなな with the last な dropped.

The [の](https://dictionary.goo.ne.jp/word/%E3%81%AE/#jn-171157) here is 準体助詞

So yes, の is nominalizing あんな.

Generally a particle connects to specific forms of verbs (possibly comparable
to prepositions connecting to specific cases of nouns in some European
languages).

The relevant definition of に is:

> ［格助］名詞、名詞に準じる語、動詞の連用形・連体形などに付く ５ 動作・作用の目的を表す。「見舞い―行く」「迎え―行く」

For the particular case, 見 is 連用形, not infinitive form (I assume it to mean
stem).

Practically "Verb (連用形) + に行く" means "go to/and V". From foreigners' grammar
perspective, 連用形 covers both te-form and masu-form. And the form that comes
before に行く is masu-form. Hopefully someone corrects me if I'm wrong.
