Questions & Answers about jeonyeoge chinguwa keopireul masyeoyo.

Why do we use 에 after 저녁?

In Korean, 에 is the particle that marks a point in time when something happens. 저녁 means “evening,” so 저녁에 literally means “in the evening” or “at evening.” Whenever you want to say “at 3 o’clock,” “on Monday,” or “in the morning,” you similarly add 에 (e.g. 3시에, 월요일에, 아침에).

What is the role of 와 in 친구와?

와 is the particle meaning “with.” It attaches to words ending in a vowel.

• If a noun ends in a consonant, you use 과 instead (e.g. 선생님과).
• In casual speech, many Koreans prefer 랑 (친구랑) or 하고 (친구하고), but 와/과 is more formal or written.

Why is 커피 followed by 를?

를 is the object marker (after a vowel-ending noun). It tells us that 커피 is the direct object of 마시다 (“to drink”). If the noun ends in a consonant, you would use 을 instead.

Why is the subject missing, and who is drinking the coffee?

Korean often omits subjects when they’re understood from context. Here, because of the polite ending -요, the default assumption is “I.” If you needed to be explicit, you could say:
저는 저녁에 친구와 커피를 마셔요.
