Questions & Answers about watasi ha hitori de nihongo wo benkyousimasu.
Why is 私 marked with は instead of が? Can I use が here?
は is the topic marker, introducing what the sentence is about (“as for me…”). が is the subject marker, often used to present new information or emphasize the doer. In this sentence you’re stating your own topic (your study habit), so 私 takes は. If you switch to が – 私が一人で日本語を勉強します – it sounds like you’re contrasting “I (and not someone else) will study Japanese alone,” which is less natural here.
What does 一人で mean? Why is で used after 一人?
一人 means “one person” or “alone.” The particle で marks the means or condition. So 一人で literally means “in the state of one person,” i.e. “by myself” or “alone.” You use で because you’re indicating the manner in which you study.
Why is 日本語 marked with を? I thought を sometimes indicates place.
Here を is the direct‐object marker: “Japanese language” is what you’re studying. While を can also mark a path or location (like 公園を散歩する, “walk through the park”), with verbs like 勉強する it marks the thing you study.
Why do we say 勉強します instead of just 勉強? What’s the structure here?
勉強 is a noun (“study”). Adding する turns it into a verb, “to study.” In polite form, する becomes します, so 勉強します means “study.” You can’t leave off します if you want a complete verb.
What tense is 勉強します? Does it mean “I study,” “I am studying,” or “I will study”?
Japanese polite present-tense 勉強します covers both “I study” (habitually) and “I will study.” There’s no separate future form. Context tells you whether it’s habitual (“I study Japanese alone”) or a plan (“I will study Japanese alone [later]”).
Can I drop 私は entirely and just say 一人で日本語を勉強します?
Yes. In Japanese, when the topic is clear you often omit pronouns. 一人で日本語を勉強します still means “I study Japanese by myself,” as long as it’s clear you’re talking about yourself.
Is this sentence in the SOV order? How rigid is word order in Japanese?
Yes: Topic (私＋は), manner (一人＋で), object (日本語＋を), then verb (勉強します). Japanese is fairly flexible, but the verb almost always comes last. Particles tell you each word’s role, so you can sometimes reorder for emphasis, but the basic flow remains topic–(adverbials)–object–verb.
How do I pronounce this sentence in romaji and with proper accent?
Romaji: Watashi wa hitori de nihongo o benkyō shimasu.
Notes:
• にほんご (nihongo) – low-high-low pitch pattern.
• べんきょう (benkyō) – low-high pitch.
• The を particle is pronounced “o,” not “wo.”
