Questions & Answers about Teman saya adalah desainer grafis.

Why does saya come after teman instead of before, like in English?

In Indonesian, possession is usually shown by putting the possessor after the noun:

• teman saya = my friend (literally: friend I)
• ibu saya = my mother
• rumah saya = my house

So teman saya means my friend, not I am a friend.
Putting saya first would change the meaning:

• saya teman = I am a friend (rare, and sounds incomplete without more context)
• saya adalah teman dia = I am his/her friend

For possession, keep the pattern noun + pronoun: teman saya, buku kamu, mobil dia, etc.

Do I really need adalah in this sentence? Can I just say Teman saya desainer grafis?

You do not need adalah here. Both of these are grammatically correct:

• Teman saya adalah desainer grafis.
• Teman saya desainer grafis.

Difference in feel:

• With adalah – more formal, typical in writing, presentations, or careful speech.
• Without adalah – more natural in everyday conversation.

So if you are speaking casually, Teman saya desainer grafis is very common and perfectly fine.
