Learn Hardcore Norwegian: Jeg snakker om en bok.

No, you typically do not capitalize jeg in Norwegian unless it appears at the beginning of a sentence. Unlike in English, the Norwegian first-person singular pronoun remains lowercase.

Why is it "en bok" (a book) instead of "et bok"?

Nouns in Norwegian can be either masculine, feminine, or neuter. The word bok is generally treated as a feminine or masculine noun and therefore takes the indefinite article en. If it were a neuter noun, you would use et instead, but bok is not neuter.

How should I understand the preposition "om" in "Jeg snakker om en bok"?

In this sentence, om means "about." So snakker om translates to "talk about" in English. In Norwegian, om is often used in contexts where you discuss a topic, just as you might use "about" in English.

Why do we say "snakker" instead of "snakke"?

Snakker is the present tense conjugation of the verb snakke (to speak) when using the pronoun jeg. In Norwegian, the present tense form for most verbs adds an -r at the end, regardless of the subject (jeg/du/vi, etc.). For example, jeg snakker, du snakker, vi snakker, and so on.
