Reformulation gives the reader a second route to the same intended content. Yaitu and yakni specify what a preceding general expression refers to; dengan kata lain restates an idea in different words. For genuine correction, Indonesian often adds lebih tepatnya “more precisely” or atau, tepatnya, “or, more precisely.” These expressions connect discourse units—they do not become copular predicate verbs.
The crucial distinction is between specification and paraphrase. Naming the three items in a list is not the same operation as explaining a technical sentence more accessibly. See Apposition and Explanatory Noun Phrases for the noun-phrase structures that often surround yaitu and yakni.
The reformulation map
| Marker | Operation | Typical register |
|---|---|---|
| yaitu | identifies the exact referent or content | neutral-formal |
| yakni | specifies with a slightly more formal/written tone | formal |
| dengan kata lain | paraphrases the preceding proposition | neutral-formal |
| lebih tepatnya | replaces an imprecise formulation with a more exact one | neutral-formal |

Kami tiba pada sore hari—lebih tepatnya, pukul setengah enam.
We arrived in the late afternoon—more precisely, at half past five. (correction)
yaitu: exact appositional specification
Yaitu introduces the exact identity, content, or members anticipated by a preceding general expression (neutral-formal).

One requirement has not been met, namely the building owner's letter of approval.

The real problem lies in one thing, namely how the budget is allocated.
The fourth example shows why the antecedent must predict a specification. After bukan kekurangan dana, yaitu does not repair the contrast cleanly; melainkan is needed. A reformulator cannot replace the logical relation.
In well-formed use, the expression before yaitu opens a slot—satu syarat, opsi kedua, tujuan—and the following unit fills it.
Definition with yaitu
For definitions, use a frame that introduces a term or general category, then specify it.
Istilah literasi digital merujuk pada seperangkat kemampuan, yaitu kemampuan menemukan, menilai, dan menggunakan informasi digital secara bertanggung jawab.
The term digital literacy refers to a set of abilities, namely the ability to find, evaluate, and use digital information responsibly. (definition)
Yang dimaksud dengan biaya tetap adalah biaya yang tidak berubah ketika jumlah produksi berubah dalam rentang tertentu.
What is meant by fixed cost is a cost that does not change when production volume changes within a certain range. (formal definition)
In stricter edited prose, adalah often gives the cleanest direct definition: Biaya tetap adalah biaya yang.... Yaitu is most transparent when it visibly specifies an antecedent rather than standing where English uses “is.”
yakni: formal written specification
Yakni performs much the same appositional operation as yaitu but often sounds more formal, concise, or written (formal).

Kedua pihak menyepakati waktu pertemuan, yakni Senin pagi pukul sembilan.
Both parties agreed on the meeting time, namely Monday morning at nine. (formal)
There is no deep truth-conditional difference between yaitu and yakni in these examples. The choice is stylistic. Do not alternate them merely to appear sophisticated; consistency is often better.
Introducing a list
Both markers can introduce a list when the preceding phrase predicts a known number or class.

The committee provides three payment options: bank transfer, debit card, and digital wallet.

Participants must submit two documents: a passport and a letter of acceptance.
The list is exhaustive because tiga, empat, and dua establish a complete count. For an open list, antara lain is usually more appropriate.
dengan kata lain: same proposition, new wording
Dengan kata lain is a three-word sentence connector meaning “in other words” (neutral-formal). It normally begins a new sentence and takes a following comma.
Perjanjian itu diperpanjang secara otomatis kecuali salah satu pihak menyatakan berhenti. Dengan kata lain, diam dianggap sebagai persetujuan untuk melanjutkan.
The agreement renews automatically unless one party opts out. In other words, silence is treated as agreement to continue.
Sistem hanya menyimpan versi terbaru berkas. Dengan kata lain, perubahan lama tidak dapat dipulihkan dari aplikasi.

Nominal income growth was lower than inflation. In other words, household purchasing power actually declined. (economic explanation)
The second sentence should preserve the first sentence's claim while changing its conceptual packaging. If it adds a new consequence instead, use a consequence marker.
Making technical prose accessible
Nilai absolut koefisien elastisitas permintaan kurang dari satu, sehingga persentase perubahan kuantitas yang diminta lebih kecil daripada persentase perubahan harga.
The absolute value of the demand-elasticity coefficient is below one, so the percentage change in quantity demanded is smaller than the percentage change in price. (technical)
Dengan kata lain, pembeli tidak banyak mengubah jumlah pembelian ketika harga naik atau turun sedikit.
In other words, buyers do not change how much they purchase very much when the price rises or falls slightly. (accessible rewrite)
Model menerapkan pembobotan terbalik terhadap frekuensi kemunculan istilah.
The model applies weighting inversely related to how frequently a term occurs. (technical)
Dengan kata lain, kata yang jarang muncul mendapat bobot lebih besar daripada kata yang sangat umum.
In other words, rare words receive more weight than very common words. (accessible rewrite)
Good reformulation changes wording and assumed knowledge, not the underlying claim.
Correction with lebih tepatnya
Lebih tepatnya replaces a rough statement with a more accurate one (neutral-formal). It may begin a new sentence or appear parenthetically.
Mereka tinggal di Jakarta—lebih tepatnya, di Tangerang Selatan.
They live in Jakarta—or more precisely, in South Tangerang.
Pertemuan berlangsung selama dua jam, atau lebih tepatnya, satu jam empat puluh lima menit.
The meeting lasted two hours—or, more precisely, one hour and forty-five minutes.
Proyek itu tertunda. Lebih tepatnya, tahap pengadaanlah yang belum dapat dimulai.
The project is delayed. More precisely, it is the procurement stage that has not yet begun.
Unlike dengan kata lain, correction admits that the first formulation was approximate or overbroad.
Comma or colon?
A comma normally precedes yaitu/yakni when the reformulator remains inside the sentence.
Kami memilih satu lokasi, yaitu gedung perpustakaan lama.
We selected one location, namely the old library building.
A colon can replace the reformulator when a complete clause explicitly anticipates a specification or list.
Kami memilih satu lokasi: gedung perpustakaan lama.
We selected one location: the old library building.
Rapat menghasilkan tiga keputusan: jadwal diubah, anggaran ditinjau, dan ketua tim diganti.
The meeting produced three decisions: the schedule was changed, the budget was reviewed, and the team leader was replaced.
Avoid piling both signals together as yaitu: in ordinary continuous prose. Sentence-opening Dengan kata lain, takes a comma, and the multiword expression remains separate.
Common Mistakes
1. Treating yaitu as a copular verb
❌ Rani yaitu dokter gigi di klinik baru itu.
Incorrect direct identification—yaitu is a reformulator, not the predicate verb equivalent of is.
✅ Rani adalah dokter gigi yang bekerja di klinik baru itu.
Rani is a dentist who works at the new clinic. (formal identification)
2. Using yaitu after an antecedent that predicts contrast
❌ Hambatannya bukan biaya, yaitu waktu yang sangat terbatas.
Incorrect relation—bukan requires a correction such as melainkan, not appositional specification.
✅ Hambatannya bukan biaya, melainkan waktu pelaksanaan yang sangat terbatas.
The obstacle is not cost but the very limited implementation time.
3. Using dengan kata lain for a new consequence
❌ Hujan turun semalaman. Dengan kata lain, pertandingan dibatalkan.
Wrong relation—the cancellation is a consequence, not a paraphrase of the rain.
✅ Hujan turun semalaman. Akibatnya, pertandingan pagi dibatalkan.
It rained all night. As a result, the morning match was canceled.
4. Writing the multiword connector solid
❌ Dengankatalain, biaya tambahan itu tidak dapat dikembalikan.
Incorrect spacing—dengan kata lain is three words.
✅ Dengan kata lain, biaya tambahan tersebut tidak dapat dikembalikan setelah pembayaran.
In other words, the additional fee cannot be refunded after payment.
5. Doubling the list introduction
❌ Tim menilai tiga aspek, yaitu: biaya, waktu, dan risiko.
Overmarked continuous prose—the comma, yaitu, and colon duplicate the same boundary.
✅ Tim menilai tiga aspek, yaitu biaya, waktu, dan risiko pelaksanaan.
The team assesses three aspects: cost, time, and implementation risk.
