Comparative and Superlative

Dutch comparatives and superlatives follow a clean pattern: -er for the comparative, -st or -ste for the superlative. Plus a handful of irregulars (notably goed → beter) and a few specific rules for “than” (dan) and “as … as” (even … als).

The comparative

To compare two things, Dutch adds -er to the adjective stem.

Spelling adjustments

Some spelling shifts happen when adding -er:

Long vowels in open syllables. When the syllable opens (because -er adds a vowel), Dutch drops a doubled vowel:

Short vowels: double the consonant.

Adjectives ending in -r: add -d before -er.

This -rd- form (duurder) is to preserve clear pronunciation.

The “than” word — dan

For comparisons, use dan as the “than” word.

Hij is groter dan ik. — He is taller than I. Amsterdam is groter dan Rotterdam. — Amsterdam is bigger than Rotterdam.

Note: in Dutch, after dan, you can use either the subject or the object form of the pronoun, depending on register. Hij is groter dan ik (formal) or Hij is groter dan mij (colloquial — but considered substandard by some). The Dutch grammar police prefer dan ik.

Als — common but contested

In some regional Dutch, als is used instead of dan for comparisons:

Hij is groter als ik. — He is taller than me.

This is incorrect in standard Dutch but widespread in spoken Belgian Dutch and some southern Netherlands dialects. Stick with dan for written and formal Dutch.

The superlative

To form the superlative, add -st (or -ste depending on context) to the adjective.

Attributive vs. predicative

There are two superlative constructions in Dutch.

Attributive (before a noun): add -st + the standard adjective endings (-e or bare, depending on de/het rule). Always with the definite article de or het.

de grootste boom — the biggest tree het mooiste schilderij — the most beautiful painting de oudste kerk — the oldest church

Predicative (after a copula): use het + -st (no -e):

Deze boom is het grootst. — This tree is the biggest. Dat schilderij is het mooist. — That painting is the most beautiful.

Note: het + adjective + -st is the predicate-superlative pattern. The het is fixed (doesn’t agree with the noun) and the adjective takes no -e.

This het + -st superlative is one of the most distinctive Dutch constructions. Without het, the sentence doesn’t sound right.

The four irregulars

A small set of common adjectives have irregular comparatives and superlatives. Memorise them.

Goed → beter → best is the most common. Erger and minder and meer appear constantly.

For adverbs derived from these:

Liever and het liefst are essential for expressing preferences: Ik drink liever koffie dan thee (I prefer coffee to tea).

Even … als — the “as … as” construction

For equal comparisons, use even + adjective + als or zo + adjective + als:

Hij is even groot als ik. — He is as tall as me. Het boek is zo lang als de andere. — The book is as long as the other.

Both even and zo work. Even is slightly more common in modern Dutch.

For “not as … as,” use niet zo … als:

Hij is niet zo groot als ik. — He is not as tall as me.

What you don’t need to do

You don’t need to translate dan and als as separate concepts. They’re both about comparison; dan is the “than” of inequality, als the “as” of equality.

You don’t need to memorise every spelling shift. The patterns (drop doubled vowel, double the consonant) apply consistently.

You don’t need to use als for comparisons in writing. Stick with dan.

Common confusions

• Dan vs. als. Dan for inequality (taller than, faster than). Als for equality (as tall as) or for if (entirely different word).
• Het in predicate superlatives. De boom is het grootst, not De boom is grootst. The het is fixed.
• Spelling shifts. Groot → groter (drop one o). Dik → dikker (double the k). These follow the same rules as plurals.
• Irregular comparatives are limited. Beter, erger, meer, minder, liever — the main ones. Most adjectives are regular.

Where you’ll meet it in the library

Comparative and superlative appear constantly. Especially visible in:

• The Low Countries (A2+) — Storica’s book ranks cities, paintings, kings, ages. Groter dan, het grootste, beter dan, de beste. Reading any historical-comparison passage drills the system.
• Any Dutch travel guide, sports report, or product review. The comparison structures are everyday workhorses.
