Notes & Nuances

📌 Important Points

Used with Like/Dislike
With ‘suki’ (like) and ‘kirai’ (dislike), ‘ga’ is used for the thing being liked/disliked.
Example: リンゴが好きです。(I like apples.)
Existence Verbs
The subject of existence (imasu/arimasu) is always marked with ‘ga’.
Example: 猫がいます。(There is a cat.)
Question Words as Subjects
When the subject is an unknown question word, you must use ‘ga’.
Example: 誰が食べましたか。(Who ate it?)

⚠️ Common Mistakes

❌ 誰は来ますか。(Dare wa kimasu ka)
✅ 誰が来ますか。(Dare ga kimasu ka)
Question words like ‘dare’ (who) or ‘nani’ (what) must be followed by ‘ga’ when they are the subject, never ‘wa’.
❌ 日本語を分かります。(Nihongo wo wakarimasu)
✅ 日本語が分かります。(Nihongo ga wakarimasu)
The verb ‘wakarimasu’ (to understand) usually takes ‘ga’, not ‘wo’, because it describes a state of understanding.

🏛️ Cultural Context

Politeness Level: Neutral/Foundational. Its usage doesn’t change based on politeness, but choosing between ‘wa’ and ‘ga’ reflects the speaker’s nuance.
Social Situations: Used in all social settings. ‘Ga’ is more objective and descriptive than ‘Wa’.
Regional Variations: Standard across Japan.

🔍 Subtle Differences

は (wa) vs が (ga)
‘Wa’ marks the topic (what we are talking about), while ‘ga’ marks the subject (who does the action). ‘Wa’ focuses on the information after the particle, while ‘ga’ often focuses on the noun before it.
When to use: Use ‘wa’ for known topics and general statements. Use ‘ga’ for new information or emphasizing specific subjects.

📝 Conjugation Notes

‘Ga’ is a particle and does not conjugate. It always follows a noun or a noun-phrase.

🔊 Pronunciation Tips

In some dialects and fast speech, ‘ga’ may sound slightly like ‘nga’ (nasalized).

🧠 Memory Tips

Think of ‘ga’ as a spotlight. It shines directly on the noun before it, saying ‘This is the specific person/thing I am talking about!’
