Questions & Answers about tomodachi wa kaabubooru o nageru.
Why is は used after 友達 instead of が?
は marks 友達 as the topic of the sentence: as for the friend, they throw a curveball.
In a basic sentence like this, は often feels natural when you are simply talking about someone and saying something about them.
If you used が instead, the nuance would be different. が tends to mark the subject more directly and can sound like you are identifying who does the action, often with a sense of focus or contrast.
So:
- 友達はカーブボールを投げる。 = My/The friend throws a curveball / As for my friend, they throw a curveball
- 友達がカーブボールを投げる。 = The friend is the one who throws a curveball
Both can be grammatical, but は is the more neutral topic-marking choice here.
What does を do in this sentence?
を marks the direct object of the verb.
Here, カーブボール is the thing being thrown, so it gets を:
- カーブボールを投げる = to throw a curveball
A useful pattern to remember is:
- [thing] を [verb]
with を showing what the action is done to.
What tense is 投げる? Does it mean throws or will throw?
