A comparison sentence puts two things side by side and says how they relate: one is bigger than the other, just as fast as the other, or they move together so that the more of one, the more of the other. German has three machines for this, each with its own connector and its own grammar: als for inequality, so ... wie for equality, and je ... desto/umso for proportion. The single-word choice between als and wie is handled in detail on the Conjunctions als-vs-wie page; this page is about building full comparison sentences and clauses — especially the proportional je ... desto construction, whose double-clause word order has no English parallel and trips up nearly every learner.
Inequality: comparative + als
When one thing outranks another, German uses a comparative form (ending in -er: größer, schneller, besser, mehr) followed by als ("than"). What you compare can be a single word or a whole clause.
Mein neues Fahrrad ist leichter als mein altes.
My new bike is lighter than my old one. (comparison with a phrase — no comma)
Sie spricht besser Deutsch, als ich erwartet hatte.
She speaks German better than I had expected. (comparison with a full clause — comma, verb to the end)
Das Konzert dauerte länger, als wir gedacht hatten.
The concert lasted longer than we had thought. (clause: als + subject + … + verb-final)
The crucial difference is what follows als. With a phrase (a noun, pronoun, or adverb: als mein altes, als ich, als gestern) there is no comma and nothing moves. With a full clause (als ich erwartet hatte), German puts a comma before als and sends the verb to the end, because als is now a subordinating conjunction introducing a subordinate clause. This clause comparison — comparing against what you expected, thought, hoped — is extremely common and is where the comma and verb-final order matter.
Equality: so ... wie
When two things are equal, German brackets the base form of the adjective between so and wie: so groß wie ("as big as"). Again the standard of comparison can be a phrase or a full clause.
Der Film war so gut, wie alle gesagt haben.
The film was as good as everyone said. (equality with a clause — comma, verb-final)
Sie ist genauso ehrgeizig wie ihr Bruder.
She is just as ambitious as her brother. (equality with a phrase — genauso intensifies so)
You can strengthen so to genauso or ebenso ("just as") without changing the frame — wie still closes it. The adjective stays in its plain base form (gut, ehrgeizig), never the comparative; a comparative would force als instead. As with als, a following full clause takes a comma and verb-final order (wie alle gesagt haben).
Likeness: wie for "like / as"
Beyond measured equality, wie also means "like" — likening one thing to another in kind rather than degree.
Er rennt wie ein Profi.
He runs like a pro. (likeness — wie, never als)
Es lief alles genau so, wie wir es geplant hatten.
Everything went exactly as we had planned. (manner — wie introduces the clause)
English uses "like" or "as" here, and German always uses wie. The throughline: wie points at sameness or resemblance, als at a gap. The full single-word contrast (and the famous nonstandard größer wie) is on the als-vs-wie page.
Proportion: je ... desto / umso — the construction to master
This is the heart of the page and the part competitors gloss over. To say "the more X, the more Y" — two quantities rising or falling together — German uses je ... desto (or the interchangeable je ... umso). English does this with a doubled "the": the more I practise, the better I get. German's structure looks similar but its word order is the opposite of everything else you have learned, so it must be drilled deliberately.
The construction has two clauses:
- The je-clause comes first and is a subordinate clause — its verb goes to the end (verb-final).
- The desto/umso-clause comes second and is a main clause — its verb comes in second position (verb-second), immediately after desto/umso
- the comparative.
So the comparative word moves to the front of each clause, and the two clauses run with mirror-image verb placement: verb last in the je-clause, verb second in the desto-clause.
Je mehr ich übe, desto besser werde ich.
The more I practise, the better I get. (je-clause: verb übe at the end; desto-clause: verb werde in second position)
Je länger ich warte, umso nervöser werde ich.
The longer I wait, the more nervous I get. (umso = desto; same mirror-image order)
Je früher wir losfahren, desto mehr Zeit haben wir.
The earlier we set off, the more time we have. (comparatives früher / mehr lead each clause)
Trace the first example slot by slot. The je-clause is Je mehr ich übe — the comparative mehr opens it, then subject ich, then the verb übe in final position (subordinate order). After the comma comes the desto-clause: desto besser werde ich — desto + comparative besser fill the first slot together, then the verb werde sits in second position, then the subject ich. The verb of the second clause comes before its subject because the desto + comparative unit has already taken the Vorfeld (first position), so the verb must follow it to stay in V2.
A few practical notes. The two halves can both be very short — a fixed, almost proverbial pattern with the verbs simply dropped: Je früher, desto besser ("the sooner, the better"), Je mehr, desto besser ("the more, the merrier"). When the adjective stands before a noun it still declines normally: Je größer die Firma, desto langsamer die Entscheidungen. And desto and umso are fully interchangeable — umso is very slightly more common in speech, desto in writing, but both are neutral standard.
Je größer das Unternehmen, desto langsamer die Entscheidungen.
The bigger the company, the slower the decisions. (verbs dropped in this proverbial style; größer declines before its noun)
Quick reference
| Relation | Connector | Adjective form | Word order of a following clause |
|---|---|---|---|
| inequality ("than") | als | comparative (größer) | comma + verb-final |
| equality ("as ... as") | so ... wie | base form (groß) | comma + verb-final |
| likeness ("like / as") | wie | — | comma + verb-final (if a clause) |
| proportion ("the more, the more") | je ... desto/umso | comparative in both clauses | je-clause verb-FINAL, desto-clause verb-SECOND |
Common Mistakes
❌ Das Konzert dauerte länger wie wir dachten.
Nonstandard — länger is a comparative, so it requires als, not wie.
✅ Das Konzert dauerte länger, als wir dachten.
The concert lasted longer than we thought.
❌ Je mehr ich übe, desto ich werde besser.
Incorrect — in the desto-clause the verb must come second, right after desto + comparative: desto besser werde ich.
✅ Je mehr ich übe, desto besser werde ich.
The more I practise, the better I get.
❌ Je mehr ich lerne, desto besser ich verstehe.
Incorrect — same V2 rule: the finite verb verstehe must precede the subject ich in the desto-clause.
✅ Je mehr ich lerne, desto besser verstehe ich.
The more I learn, the better I understand.
❌ Je ich mehr übe, desto besser werde ich.
Incorrect — the comparative (mehr) must lead the je-clause, before the subject: Je mehr ich übe.
✅ Je mehr ich übe, desto besser werde ich.
The more I practise, the better I get.
❌ Sie ist so klug als ihr Bruder.
Incorrect — the equality frame so ... requires wie, not als.
✅ Sie ist so klug wie ihr Bruder.
She is as clever as her brother.
Key Takeaways
- Inequality uses a comparative + als; equality uses so ... wie with the base form; likeness uses wie.
- A full clause after als or wie takes a comma and verb-final order; a bare phrase takes neither.
- je ... desto/umso is the proportional construction: je-clause verb-final, desto-clause verb-second — a mirror-image order with no English parallel.
- In the desto-clause the verb comes before the subject, because desto + comparative already fills the first slot.
- desto and umso are interchangeable; in proverbial form the verbs can drop entirely (Je früher, desto besser).
