Questions & Answers about watashi wa shuumatsu ni tomodachi to issho ni kouen de supootsu o shimasu.

Why is there a は after 私? What does it do?

は is the topic marker. It tells you what the sentence is “about”.

• 私 は = “As for me / speaking about me…”
• In natural English we just say “I”.

In this sentence, 私 is also the subject in meaning, but Japanese separates “topic” (は) from “grammatical subject” (often marked by が). For simple “I do X” sentences, learners usually just learn X は Y です / Y を します as “I …”.

You could omit 私 entirely if it is clear from context who “I” is:

• （私は）週末に友達と一緒に公園でスポーツをします。
  = “(I) play sports at the park with my friends on the weekend.”

What’s the difference between 週末に and 公園で? Why に for one and で for the other?

They are marking different kinds of information:

• 週末 に – に marks a point in time:

  • 週末に = “on the weekend”
  • Other examples: 3時に (at 3 o’clock), 月曜日に (on Monday)

• 公園 で – で marks the place where an action happens:

  • 公園で = “at/in the park”
  • Other examples: 家で食べます (eat at home), 学校で勉強します (study at school)

So the pattern is:

[time + に] + [place + で] + [action]

週末に (when) + 公園で (where) + スポーツをします (do sports).

Why does also have after it ()? Is that the same as in ?
