Questions & Answers about watashi wa atarashii megane o kaitai.
は marks the topic of the sentence: what you’re talking about.
が normally marks the grammatical subject and often introduces new or contrasted information.
- 私は新しい眼鏡を買いたい。
→ As for me, (I) want to buy new glasses.
The speaker is presenting “me” as the topic of conversation. If you said:
- 私が新しい眼鏡を買いたい。
this would sound like you’re contrasting yourself with someone else, e.g. “I’m the one who wants to buy new glasses (not someone else).” It’s possible, but it has that added nuance and is less neutral than は here.
Yes, and that’s actually more natural in many real conversations.
Japanese often omits anything that’s clear from context: subjects, objects, even the topic. If it’s obvious that you’re talking about yourself, 新しい眼鏡を買いたい。 on its own usually means “I want to buy new glasses.”
So:
- 私 is kept when you:
- want to make the subject explicit (e.g. in writing, or to avoid confusion), or
- contrast yourself with others: 私は買いたいけど、彼は買いたくない。
“I want to buy them, but he doesn’t.”
