Japanese Particles (助詞)
Particles are small words that come after nouns, verbs, or phrases to show their role in the sentence. They are the grammar glue of Japanese. Getting particles wrong changes the entire meaning of a sentence.
は (wa) — Topic marker
Marks what the sentence is about. Think of it as “as for...” or “speaking of...”
私は学生です。
わたしはがくせいです
As for me, (I am) a student.
今日は暑いです。
きょうはあついです
As for today, (it is) hot.
が (ga) — Subject marker
Marks the subjectperforming the action. Often used to introduce new information, answer “who/what” questions, or express preferences and abilities.
猫がいる。
ねこがいる
There is a cat. (new information)
日本語が好きです。
にほんごがすきです
I like Japanese. (が marks what is liked)
は vs が — The big question
This is the most asked question in Japanese grammar. A simplified way to think about it:
Talks about something already known. Contrasts or sets a topic. “As for X...”
Introduces new information. Answers “who?” or “what?” Emphasizes the subject.
Compare:
田中さんは来ました。 — Tanaka came. (we were talking about Tanaka)
田中さんが来ました。 — Tanaka came. (answering: who came?)
を (wo/o) — Object marker
