The particle が marks the grammatical subject — the person or thing that performs the action, or the specific element being identified. It answers "who?" or "what?" and is required with certain verbs and question words. Mastering が vs は is one of the most important skills for JLPT N5.

🚀 JLPT N5 Warm-up Quiz

Q: Which sentence correctly responds to "Who is the teacher?" (先生せんせいはだれですか) ?

Answer: B (田中たなかさんが先生せんせいです). が is used for exhaustive listing — picking out one specific thing that answers the question. A with は is a general statement; C uses の (possessive) and means "Tanaka's teacher".

📝 Core Patterns with が

Subject identification: Subject + が + Predicate + です

With verbs: Subject + が + Verb

Question words: だれ / なに / どれ + が + Predicate + か

Neutral description: Topic + は + Part + が + Adjective/Verb (象ぞうは鼻はなが長ながい)

⚠️ が points to the specific subject doing the action or being identified. It answers "exactly who/what?"

What is が?

が is the subject marker particle. It marks the grammatical subject of the sentence — the person or thing that performs the action (for intransitive verbs) or the specific entity being described or identified. It often answers the question "who?" or "what?" and is used widely in neutral descriptions and with certain verbs/adjectives.

Always pronounced が (ga) — no exceptions.
Used with question words (だれが, なにが, どれが).
In neutral description sentences: marks the subject of observation.

あっ、鳥とりがいますよ！あっ、とりがいますよ！A, tori ga imasu yo!
Oh, there's a bird! (neutral description of something observed)

⚡ Three Main Functions of が

Function	Explanation	Example
Exhaustive Listing (排他)	Picks out one specific thing — "it is THIS one" (answer to a question).	私わたしが学生がくせいです。わたしががくせいです。Watashi ga gakusei desu. I am the student.
Neutral Description (中立叙述)	Describes a scene or state objectively — often with verbs like いる/ある and weather.	雨あめが降ふっています。あめがふっています。Ame ga futte imasu. It's raining.
Subject of Potential/Intransitive	Marks the subject with verbs of ability (できる) or adjectives like すき/きらい.	私わたしは英語えいごができます。わたしはえいごができます。Watashi wa eigo ga dekimasu. I can speak English.

Examples & Mini Dialogue

だれが教室きょうしつにいますか。だれがきょうしつにいますか。Dare ga kyōshitsu ni imasu ka.
Who is in the classroom? (question word だれ + が)

✅ だれ (who) must use が, not は.

妹いもうとはピアノが上手じょうずです。いもうとはぴあのがじょうずです。Imōto wa piano ga jōzu desu.
My younger sister is good at piano. (topic は + specific trait が)

🗣️ Mini Dialogue
A: どのペンを使つかいますか。どのぺんをつかいますか。Dono pen o tsukaimasu ka.
(Which pen will you use? — transitive verb 使う takes を)

B: 赤あかいペンが好すきです。あかいぺんがすきです。Akai pen ga suki desu.
(I like the red one — すき takes が)

⚡ が (subject) vs は (topic) — Quick Decision Guide

Situation	Use	Example
General statement about a topic	は	私わたしは学生がくせいです。
Answering "who/what specifically?"	が	私わたしが学生がくせいです。
With question words (だれ, なに等)	が	だれが来きますか。
Neutral observation (weather, scene)	が	雨あめが降ふっています。
With すき / きらい / できる / じょうず	が	英語えいごができます。
Direct object of a transitive verb (使う, 食べる等)	を	ペンを使つかいます。

⚠️ Critical JLPT Trap: With verbs like すき, きらい, できる, ほしい, じょうず, the object is marked by が, not を. However, for ordinary transitive verbs like 使う, 食べる, 見る, use を — not が.

Common Mistakes (and Fixes)

✕ だれは先生せんせいですか。

✓ だれが先生せんせいですか。 (Question words must use が.)

✕ 私わたしは英語えいごをできます。

✓ 私わたしは英語えいごができます。 (できる takes が, not を.)

✕ どのペンが使つかいますか。

✓ どのペンを使つかいますか。 (Transitive verbs like 使う take を for their direct object, not が.)

✕ 今日きょうは雨あめは降ふっています。

✓ 今日きょうは雨あめが降ふっています。 (Neutral observation uses が for the subject.)

JLPT N5 Practice Questions

Score: 0 / 3

1. "Who is Tanaka?" Choose the correct particle.

2. "I like cats." Which particle do you use after the thing you like?

3. "Which pen will you use?" — transitive verb 使う takes which particle?

🎯 JLPT N5 tip: が vs は is one of the top 3 most‑tested grammar points. Remember: question words + が, neutral descriptions + が, and すき・できる always take が. But transitive verbs (使う, 食べる) take を for their object.

Frequently Asked Questions

Why does すき use が and not を?

In Japanese, すき and きらい are adjectives (likeable/dislikeable), not action verbs. The thing you like is the subject that "is likeable" to you. So it takes が — just like how "I am good at English" is 英語ができる.

Can a sentence have both は and が?

Yes, often. は marks the overall topic, and が marks the specific subject or object of a sub‑clause. Example: 象は鼻が長い (As for elephants, their noses are long).

When I answer a question, should I use は or が?

If the question word was the subject (who, what), use が in the answer. だれが先生ですか？→ 田中さんが先生です. If the question asked about a topic, use は. 田中さんは何ですか？→ 田中さんは先生です.

How do I know whether a verb takes が or を?

Transitive verbs (actions done to something) take を: 食べる, 使う, 見る. Intransitive verbs and adjectives like すき/できる take が. When in doubt, check if it's an action verb with a direct object — if so, use を.
