Questions & Answers about watasi ha eki de koohii wo kaimasu.
Why is the particle は pronounced “wa” in this sentence?
When は is used as a grammatical topic marker, its pronunciation shifts from ha to wa. This is a historical relic in Japanese: the spelling remains は, but whenever it marks the topic, you say wa.
What is the role of は in 私 は 駅 で コーヒー を 買います?
は marks 私 (“I”) as the topic of the sentence. It tells the listener that the statement is about “me,” setting up the rest of the information (where and what I’m buying).
What does the particle で indicate in 駅で?
で marks the location where an action takes place. So 駅で means “at the station,” specifying where the buying happens.
What function does を serve in コーヒーを買います?
を marks the direct object of the verb. Here it shows that コーヒー (“coffee”) is the thing being bought.
Why does the verb 買います appear at the end of the sentence?
Japanese uses a Subject–Object–Verb (SOV) word order. The verb naturally comes last, after the topic/subject and any objects or modifiers.
What form is 買います, and what nuance does it add?
買います is the polite present/future form of 買う (“to buy”). The –ます ending makes the statement courteous, and context tells you whether it’s a habitual action (“I buy”) or a planned/future action (“I will buy”).
Do you always need to say 私 は? Can you drop it?
In casual Japanese, pronouns are often omitted if the subject is clear from context. You could simply say 駅でコーヒーを買います and it would still mean “I buy coffee at the station,” assuming the listener knows you’re talking about yourself.
