The standard is the person, thing, time, or situation against which something is compared. In Lan cao hơn tôi, tôi is the standard. Vietnamese usually places a simple standard directly after hơn. When the standard needs to be introduced as the topic of comparison—especially in reports, explanations, and careful speech—use so với “compared with/to”: So với năm ngoái, doanh thu năm nay cao hơn.
The key is not to translate English than mechanically. Hơn already forms the ordinary comparative; so với frames the reference point. This page focuses on choosing and placing standards. The opposite-scale pattern with kém is reserved for Less-Than Comparison with Kém.
A simple standard after hơn
The unmarked frame is:
A + gradable predicate + hơn + B
Anh ấy cao hơn tôi.
He is taller than me.
Chiếc áo màu xanh đắt hơn chiếc màu trắng.
The blue shirt is more expensive than the white one.
Tháng này bận hơn tháng trước.
This month is busier than last month.
The standard follows hơn without a separate equivalent of English than. A noun can be omitted where context makes it recoverable: chiếc màu trắng means “the white one,” with áo understood.
Vietnamese adjective predicates do not need là. Anh ấy cao hơn tôi is a complete clause, even though English requires is.
What so với does
So với + standard means “compared with/to + standard.” It can appear before the main clause or after its topic. It tells the listener which baseline to use before the comparative claim arrives.
So với mùa hè năm ngoái, mùa hè năm nay nóng hơn.
Compared with last summer, this summer is hotter.
Giá thuê ở khu này, so với trung tâm, thấp hơn khá nhiều.
Rent in this area, compared with the city center, is considerably lower.
So với đi taxi thì đi tàu điện nhanh hơn vào giờ cao điểm.
Compared with taking a taxi, taking the metro is faster during rush hour.
In each example, so với makes the standard a frame for the whole proposition. The later hơn still marks the predicate as comparative. In concise conversational comparisons, use direct hơn B; in analytical comparisons with a long or previously discussed baseline, so với B, A...hơn is often clearer.
Do not double a simple standard without a reason
Learners sometimes produce Lan cao hơn so với Mai because English has taller than Mai. It is understandable and examples of hơn so với occur, especially where the writer emphasizes a measured difference, but it is heavy for a basic two-person comparison. Prefer one of these:
| Choice | Model | Use |
|---|---|---|
| direct standard | Lan cao hơn Mai. | ordinary, concise comparison |
| fronted frame | So với Mai, Lan cao hơn. | Mai is the selected baseline |
| explicit measured report | Lan cao hơn Mai năm xăng-ti-mét. | states the difference |
| contextual standard | Lan cao hơn. | baseline already obvious |
So với Mai, Lan cao hơn nhưng chạy chậm hơn.
Compared with Mai, Lan is taller but runs more slowly.
The one frame so với Mai can scope over both comparisons. Repeating Mai after each hơn would be grammatical but unnecessarily heavy.
Standards can be times, expectations, and earlier states
A standard need not be another person or object.
Sức khỏe của bà tốt hơn trước.
Her health is better than before.
Buổi họp kết thúc sớm hơn dự kiến.
The meeting ended earlier than expected.
Kết quả lần này tốt hơn tôi nghĩ.
This time's result is better than I thought.
Trước supplies an earlier-state standard. Dự kiến and tôi nghĩ supply expected standards. English often uses a full than-clause; Vietnamese can place the compact expression directly after hơn. When the standard clause is long, framing can improve clarity:
So với những gì chúng tôi dự đoán lúc đầu, chi phí thực tế thấp hơn.
Compared with what we initially predicted, the actual cost is lower.
Here những gì chúng tôi dự đoán lúc đầu is a complex baseline. Fronting it keeps the main assertion chi phí thực tế thấp hơn easy to process.
Scope: what exactly is being compared?
Comparison is not only about word order; it is about parallel interpretation.
Minh nói tiếng Việt tốt hơn Nam.
Minh speaks Vietnamese better than Nam does.
This normally compares Minh and Nam as speakers. But Minh thích tiếng Việt hơn Nam can mean either “Minh likes Vietnamese more than he likes Nam” or “Minh likes Vietnamese more than Nam does.” Expand the intended standard:
Minh thích tiếng Việt hơn là Nam thích tiếng Việt.
Minh likes Vietnamese more than Nam does.
Minh thích tiếng Việt hơn là thích tiếng Anh.
Minh likes Vietnamese more than he likes English.
The first spells out a full standard clause to make Nam a second experiencer. The second contrasts two preferences. In both, là introduces the clausal standard or alternative after hơn; it is not a copula before an adjective.
Formal data comparisons need the same parallelism. Comparing this year's revenue with “the company” is illogical; compare revenue with revenue or this year with last year:
So với cùng kỳ năm ngoái, doanh thu quý này cao hơn mười phần trăm.
Compared with the same period last year, this quarter's revenue is ten percent higher.
Nearby constructions are not alternate standards
The comparison system includes several distinct relations:
| Model | Meaning | Why it differs |
|---|---|---|
| cao hơn tôi | taller than me | tôi is a lower standard on a scale |
| đẹp nhất lớp | prettiest in the class | lớp is the comparison set, not one standard |
| bằng nhau | equal to each other | no participant ranks higher |
| càng học càng hiểu | the more one studies, the more one understands | two changing degrees covary |
| ai cũng biết | everyone knows | ai...cũng ranges over people |
| mỗi người một việc | one task per person | mỗi distributes tasks individually |
These forms show why Vietnamese cannot be mapped word by word onto English determiners and adjective morphology. Mỗi, mọi, từng, đều, cả, and cũng differ in scope. They do not introduce comparison standards and should not be inserted merely because an English translation contains each, every, or all.
Dialogue: switching the baseline
A: Cậu thấy căn hộ này thế nào? B: So với căn hôm qua, căn này sáng hơn và gần ga hơn. A: Nhưng tiền thuê cũng cao hơn. B: Đúng, nếu so với ngân sách của mình thì hơi đắt.
A: What do you think of this apartment? B: Compared with yesterday's one, this one is brighter and closer to the station. A: But the rent is higher too. B: Right—compared with our budget, it's a little expensive.
The first so với sets yesterday's apartment as the baseline for physical qualities. A's cao hơn leaves that same baseline implicit. B then changes the standard to the group's budget; the final judgment is no longer a ranking of two apartments but an assessment against affordability. So với is useful precisely because it announces that change of frame.
A quick choice guide
- A short, ordinary comparison? Use predicate + hơn + standard.
- A long standard, a report, or a baseline that changes? Put so với + standard first.
- The standard is already obvious? Use predicate + hơn alone.
- The intended meaning is “less/not as good”? Do not force hơn; use the dedicated kém or negative-equative pattern.
Common Mistakes
1. Adding a copula
❌ Lan là cao hơn tôi.
Incorrect: a Vietnamese adjective can serve directly as the predicate.
✅ Lan cao hơn tôi.
Lan is taller than me.
Là is not an all-purpose translation of English is.
2. Translating than twice
❌ Lan cao hơn hơn tôi.
Incorrect: the second hơn redundantly tries to translate English ‘than.’
✅ Lan cao hơn tôi.
Lan is taller than me.
One hơn forms the ordinary comparison and introduces its standard. If the baseline needs focus, restructure it: So với tôi, Lan cao hơn. The attested sequence hơn so với can occur in heavier measured or contrastive prose, but it is not the beginner template for every English than phrase.
3. Comparing unlike things
❌ So với năm ngoái, công ty năm nay cao hơn.
Incorrect: the company itself is not higher; the measured property is missing.
✅ So với năm ngoái, doanh thu của công ty năm nay cao hơn.
Compared with last year, the company's revenue is higher this year.
Name the quantity or property whose degree changes.
4. Leaving a person/object ambiguity
❌ Tôi thích phở hơn Lan.
Ambiguous: I may like phở more than Lan does, or more than I like Lan.
✅ Tôi thích phở hơn là Lan thích phở.
I like phở more than Lan does.
For the other meaning, say Tôi thích phở hơn là thích Lan, though real contexts would normally phrase that comparison differently.
5. Confusing quantifier scope with comparison
❌ Mọi người một việc hơn.
Incorrect: hơn cannot create the intended ‘one task per person’ distribution.
✅ Mỗi người một việc.
One task for each person.
Use mỗi for individual distribution. Mọi người đều có việc means “Everyone has work/a task,” with đều distributing a predicate over the group; it does not specify one distinct task per person.
Key Takeaways
- A simple standard follows hơn directly: cao hơn tôi.
- Use so với + standard to foreground a baseline, especially when it is long, analytical, or changing.
- Hơn forms the comparison; so với frames it. Avoid stacking them mechanically in a basic sentence.
- Keep compared entities parallel and expand ambiguous standards when necessary.
