"You" in professional and casual Indonesian!
The 'Language' that we study in Duolingo is far different from our daily-life usage! This is our "Professional" language, the one we use in schools and exams.
Our "Talking" language consists of mostly slang, especially with friends.
In the professional terms, it is: "Engkau" it is used when talking to elders or people you respect. Less professional is "Kamu" but it isn't rude.
Now, if you are talking to friends, you can use "Lu"
DON'T SAY SLANG TO PEOPLE YOU RESPECT! Don't say "Lu" to your mother or anyone else, because if us Indonesians say that to our mothers, we get slapped or lectured. (I'm kidding, it's just a lecture.)
This is just a fun fact and a learning thing for those who want to speak to your friends, have a good day!! ^_^
Hello, We Indonesians say "you" in many ways. There are:
Kamu (Formal/Non-formal) used to say you to your friends, your colleague, your teacher, etc.
Anda (Formal) used to say you to stranger in same age, don't say it to someone older than you.
Kau (Non-formal) its an abreviation from word "engkau". Used to say you to your friends, don't say it to someone older than you.
Lu (Very non-formal) and only used in Jakarta Region (our capital).
In formal settings, you can use "Anda" or the honorific "Bapak" or "Ibu" (or other honorifics as appropriate) to refer to the second person.
I'd like to invite you to my wedding.
