친구 means friend. In this sentence, -랑 means with, so 친구랑 means with a friend.

-랑 can also mean and when it connects two nouns:

• 빵이랑 우유 = bread and milk

So here, because it shows the person you are doing the action with, it means with.

Because 친구 ends in a vowel, Korean uses -랑.

The pair is:

• after a consonant: -이랑
• after a vowel: -랑

Examples:

• 친구랑
• 선생님이랑

So 친구이랑 is not correct.

Yes. All of these can mean with a friend:

• 친구랑
• 친구하고
• 친구와

The difference is mostly tone and style:

• -랑 / -이랑: very common in everyday speech, slightly casual
• -하고: also very common in speech
• -와 / -과: a bit more formal or written

So 친구랑 카페에서 차를 마셔요 sounds very natural in conversation.

Because -에서 marks the place where an action happens.

Here, the action is 마셔요 = drink, and the drinking happens at the cafe, so you use 카페에서.

Compare:

• 카페에 가요 = go to the cafe
  → 에 marks destination
• 카페에서 차를 마셔요 = drink tea at the cafe
  → 에서 marks location of action

So 카페에서 is the correct choice here.

Yes, -에서 can also mean from in some sentences.

For example:

• 학교에서 집까지 가요 = I go from school to home

But in 카페에서 차를 마셔요, it clearly marks the place where the action happens, because drinking tea from the cafe would not make sense here.

So the meaning is at/in the cafe, not from the cafe.

-를 is the object marker. It shows that 차 is the thing being drunk.

So:

• 차 = tea
• 차를 = tea as the direct object of the verb

Korean uses:

• -를 after a vowel
• -을 after a consonant

Examples:

• 차를 마셔요
• 물을 마셔요

It can mean either tea or car, depending on context.

In this sentence, it means tea because the verb is 마셔요, which means drink.

So:

• 차를 마셔요 = drink tea
• 차를 타요 = ride in a car

Context usually makes the meaning clear.

Because Korean normally puts the verb at the end.

A very common Korean sentence pattern is:

subject/topic + place + object + verb

So this sentence is structured like:

• 친구랑 = with a friend
• 카페에서 = at a cafe
• 차를 = tea
• 마셔요 = drink

A very literal English-style order would be:

• With a friend at a cafe tea drink

That sounds strange in English, but it is normal in Korean.

Korean often leaves out the subject when it is obvious from context.

So 친구랑 카페에서 차를 마셔요 can naturally mean:

• I drink tea with a friend at a cafe
• I am drinking tea with a friend at a cafe

If you want to include the subject, you can say:

• 저는 친구랑 카페에서 차를 마셔요

But in everyday Korean, leaving it out is very common.

마셔요 is in the polite everyday style, often called -아요/어요 style.

It is:

• polite
• natural
• very common in conversation

Compare:

• 마셔 = casual, plain speech
• 마셔요 = polite everyday speech
• 마십니다 = formal speech

So 마셔요 is a good standard form for many situations.

The dictionary form is 마시다.

Here is the basic process:

1. Remove -다 → 마시
2. Add -어요 → 마시어요
3. This contracts to 마셔요

So:

• 마시다 → 마셔요

This is a normal contraction pattern, not a special irregular verb.

It can mean both, depending on context.

Korean present tense often covers:

• simple present: drink
• present progressive: am drinking

So 친구랑 카페에서 차를 마셔요 could mean:

• I drink tea with a friend at a cafe
• I am drinking tea with a friend at a cafe

If you want to emphasize that the action is happening right now, Korean can also use:

• 차를 마시고 있어요 = am drinking tea

Yes, it is natural.

차를 마셔요 simply means drink tea, and it is perfectly fine Korean.

In real conversation, you might also hear:

• 차 마셔요
  → the object marker -를 is sometimes dropped in casual speech
• 차 한잔 마셔요
  → drink a cup of tea
• 커피를 마셔요
  → if the speaker means coffee instead

So the sentence you have is natural and grammatically complete.

A rough pronunciation guide is:

친구랑 카페에서 차를 마셔요
chin-gu-rang ka-pe-e-seo cha-reul ma-syeo-yo

Syllable by syllable:

• 친구랑 → chin-gu-rang
• 카페에서 → ka-pe-e-seo
• 차를 → cha-reul
• 마셔요 → ma-syeo-yo

A more natural spoken rhythm is to say it smoothly as one phrase:

• 친구랑 카페에서 차를 마셔요

Romanization is only approximate, but it can help as a first step.
