Dua pertanyaan

1. Aku tahu "kemudian" dan "maka" adalah beda? Tapi aku tidak tahu kenapa. Seorang bisa jelaskan untuk saya?

i think both of them are similar, but it depends of the sentences.

kemudian in english is Then

in bahasa is kemudian or selanjutnya. Contoh/example: saya mau ke pasar besok pagi kemudian siangnya saya akan ke kampus ( i want to go to market tomorrow morning then i will go to campus in the afternoon)

you can use the word "kemudian" in case what will you do next.

My opinion about maka is similar with jadi (so)

2. Ada perbedaan antara wajib dan harus?

Wajib and harus also are similar.

"harus" is like suggestion. example" you have to study (kamu harus belajar) and there is no any punishment

"wajib" is like you really really have to do it. and sometimes there is a punishment if you don't do that

Aku harus belajar bahasa indonesia? just like suggestion or advice.

Aku wajib belajar bahasa indonesia? that means you can not to not study bahasa.

Maksudnya?

Terima Kasih!!
