Subtle Aspect
Grammar Rule in 30 Seconds
Indonesian uses particles, not verb endings, to show if an action is finished, ongoing, or planned.
- Use 'sudah' for completed actions: 'Saya sudah makan' (I have eaten).
- Use 'sedang' for ongoing actions: 'Dia sedang tidur' (He is sleeping).
- Use 'akan' for future intent: 'Kami akan pergi' (We will go).
Meanings
The aspectual system in Indonesian defines the temporal flow of an action—whether it is starting, continuing, completed, or habitual—without changing the verb's root form.
Perfective (Completed)
Indicates an action that has already occurred or a state that has been achieved.
“Proyek itu telah rampung dikerjakan.”
“Saya sudah memahami maksud Anda.”
Progressive (Ongoing)
Indicates an action currently in progress at the moment of speaking or a specific reference time.
“Ibu sedang memasak di dapur.”
“Kami tengah mendiskusikan masalah ini.”
Prospective (Future/Intent)
Indicates an action that is expected or intended to happen in the future.
“Rapat akan dimulai pukul sembilan.”
“Ia hendak menyampaikan pengumuman penting.”
Iterative/Frequentative
Indicates an action performed repeatedly or habitually, often using reduplication.
“Anak-anak berlari-larian di taman.”
“Dia memukul-mukul meja karena marah.”

The 'Belum' Secret
No 'Adalah' with Verbs
Register Matters
Experiential 'Pernah'
Smart Tips
Use 'belum pernah' instead of 'tidak pernah' if it's something you still might do one day. It sounds more optimistic!
Replace every 'sudah' with 'telah' and every 'sedang' with 'tengah' or 'sedang' (tengah is very formal).
This is the iterative aspect. It means the action is done repeatedly, for a long time, or for fun.
You can shorten it to just 'baru' in casual speech, but keep 'saja' for emphasis on the 'just this second' aspect.
発音
Stress on Aspect
In Indonesian, the stress often falls on the aspect marker if you want to emphasize the timeline.
Schwa in 'Sedang'
The 'e' in 'sedang' is a schwa /ə/, like the 'a' in 'about'.
Rising on 'Belum'
Belum? ↗
Asking 'Not yet?' with surprise or expectation.

Mnemonic
S-S-A: Sudah (Stop/Done), Sedang (Staying/Ongoing), Akan (Ahead/Future).
Visual Association
Imagine a video player. 'Sudah' is the stop button, 'Sedang' is the play button, and 'Akan' is the fast-forward button. 'Belum' is the rewind button waiting to start.
Rhyme
Sudah is done, Sedang is now, Akan is later, I'll show you how!

チャレンジ
Write 5 sentences about your morning using a different aspect marker in each sentence.
文化メモ
The use of 'lagi' instead of 'sedang' is almost universal in urban settings. Using 'sedang' in a mall might make you sound like a textbook.
Many Javanese speakers use 'baru' (just) in ways that mirror the Javanese 'nembe', often adding 'saja' for emphasis.
Official speeches heavily favor 'telah' and 'hendak' to sound authoritative and dignified.
Indonesian aspectual particles are largely derived from Austronesian roots, emphasizing the 'state' of an action rather than its placement on a linear timeline.

よくある質問 (8)
Yes, but only in specific combinations like `sudah pernah` (have already experienced) or `akan segera` (will immediately). Stacking them randomly like `sedang sudah` is ungrammatical.
`Baru saja` is more specific to the immediate past (seconds or minutes ago), while `baru` can mean 'just' or 'new'.
It's a cultural nuance. Saying `tidak` (no) sounds final and negative. `Belum` (not yet) implies that it might happen in the future, which is more polite.
Yes. In any writing that isn't a casual text or fiction dialogue, you should use `sedang` or `tengah`.
Mostly, but it can also mean 'about' in phrases like `akan hal itu` (about that matter), though this is more formal.
Use `sudah` combined with a duration. `Saya sudah tinggal di sini selama sepuluh tahun.` (I have lived/been living here for ten years).
It means 'to have the time or opportunity to do something'. `Saya sempat melihatnya` means 'I managed to see him' or 'I had the chance to see him'.
Yes! `Sudah besar` (already big), `sedang marah` (currently angry), `akan hujan` (will be rainy/will rain).
In Other Languages
Tenses (ed, ing, will)
Indonesian uses particles; English uses inflection and auxiliary verbs.
Preterite vs Imperfect
Indonesian aspect is not tied to person or number.
Le (了), Zhe (着), Guo (过)
Chinese particles often come after the verb, while Indonesian markers come before.
~te iru (~ている)
Japanese aspect is a verb suffix; Indonesian is a separate word.
Perfective vs Imperfective
Arabic is highly inflected; Indonesian is not.
Adverbs (gerade, schon)
German still requires verb conjugation for person/number.
