Indonesian has no tenses. To express idea in different time frame in English, we need to attach time signals, such as "yesterday", "tomorrow", "this morning", etc. We indicate these time signals using the verbs of English sentences.
In Indonesian, "Saya makan apel." "Saya sedang makan apel." "Saya makan apel tadi."
In English, "I eat apple." "I am eating apple." "I was eating apple."
Because of this difference, a lot of people find English to be difficult to learn because they have to memorize different forms of verbs. And these are just three of the tenses. English has 16 tenses!
