Questions & Answers about Saya beli sepeda baru kemarin.
What indicates the past tense in this sentence?
Indonesian verbs don’t inflect for tense. Instead, time adverbs do the job; here kemarin (“yesterday”) tells you it’s past.
Why is the verb beli not membeli?
Beli is the root (base) form. In everyday spoken Indonesian you can use root verbs directly. If you want a more formal or standard style, you add the active prefix meN-: membeli.
Why does baru come after sepeda?
In Indonesian (unlike English), adjectives follow the nouns they modify. So you say sepeda baru (“new bike”), not baru sepeda.
Can I move kemarin to the start of the sentence?
Yes. Indonesian word order is flexible for adverbs of time. You can say
Kemarin saya beli sepeda baru.
It still means “I bought a new bike yesterday.”
What’s the difference between saya and aku?
Both mean “I.” Saya is neutral and polite; aku is informal and used with close friends or family.
