Questions & Answers about watashi wa koohii ni gyuunyuu o sosogimasu.

Why is は used after 私 instead of が?

In Japanese は (wa) is the topic marker. It tells the listener “as for me…,” framing 私 as the topic of the conversation. By contrast, が (ga) is the subject marker, often used to introduce new information or to emphasize who is performing the action. Since you’re simply stating what you do (not emphasizing “I” over someone else), 私は is the natural choice here.

What role does に play after コーヒー?

Here に marks the target or destination of the pouring—“into the coffee.” In Japanese, when you “pour” something into a receptacle, you mark that receptacle with に.

Why is を used after 牛乳 instead of が?

The particle を (o) marks the direct object of the verb—in this case, 牛乳 (milk) is what you are pouring. が could technically mark the subject in some constructions, but here you need を to show that milk is the item being acted upon.
