Questions & Answers about watashi wa anzenna michi o erabitai to omoimasu.

What is the function of な in 安全な?

安全 is a na-adjective (形容動詞). When you use it directly before a noun (here 道), you attach な to link them:

• 安全 + な + 道 → 安全な道

Why is は used after 私 instead of が?

は is the topic marker, introducing “as for me” and setting the scene for your opinion. If you used が (私が), you’d be emphasizing “I” as the doer in a more neutral or new-information context. Here you’re simply stating your stance:

• 私は…と思います “As for me, I think…”

What role does を play before 選びたい?

を marks the direct object of the verb. In 道を選ぶ (“to choose a path”), 道 is what you’re choosing, so it takes を.

How is 選びたい formed and what nuance does it carry?

• 選ぶ (to choose) → drop -u, get stem 選び
• add たい, the desiderative suffix: 選び
  • たい → 選びたい (“want to choose”)
    This expresses the speaker’s desire to perform the action.
