  • He is a student.
    
  • 彼かれが学生がくせいです。
  • Kare ga gakusei desu.
  • He is the one who is a student.
    

In the first sentence, "彼かれ" is the topic, indicating that we are discussing "him." In the second sentence, "彼かれ" is the subject, emphasizing that "he" is the one who is a student.

Comparison and Differences

Although both は and が can mark nouns, they have different uses and meanings depending on the context.

1. Topic vs. Subject:

が	Noun + が	Used to emphasize the subject

• Kare wa uta ga jouzu desu.
• He is good at singing.
  

• 彼かれが歌うたが上手じょうずです。
• Kare ga uta ga jouzu desu.
• He is the one who is good at singing.
