Defining Grammatical Functions with Particles
- Particles attach to the end of words to define grammatical roles.
- Incorrect particles can drastically change sentence meaning (e.g., “Eat fish.” → “The fish eats.”).
The 「は」 Topic Particle
- Identifies the topic of a sentence.
- Pronounced as /wa/ when used as a particle.
- Establishes what the sentence is about without repeating the topic.
- Example: ボブ: アリスは？ → アリス: うん。 ("Is Alice (you) a student?" → "Yeah, I am.")
- Generic in scope; the topic may reference previous sentences.
The 「も」 Inclusive Topic Particle
- Adds the meaning of "also" or "too".
- Example: アリス: トムも。 ("Yeah, and Tom is also a student.")
- Maintains consistency with inclusion; use 「は」 for breaks.
- Example: アリス: でもトムはじゃない。 ("Yeah, but Tom is not a student.")
- Works with negatives: アリス: トムもじゃない。 ("No, and Tom is also not a student.")
The 「が」 Identifier Particle
- Identifies something unspecified, often used in questions.
- Example: ボブ: 誰が学生？ → アリス: ジョンが。 ("Who is the student?" → "John is the student.")
- Highlights a specific property rather than the topic:
- は: "As for me, I am a student."
- が: "I am the one who is a student."
Key Distinctions: 「は」 vs 「が」
- 「は」: Introduces a new topic ("as for").
- 「が」: Identifies something specific ("the one").
- Cannot interchange in some contexts (e.g., questions with "who").
