German Comparative Adjective Endings: Attributive Declension

German comparative adjective endings are what you add to a comparative adjective when it stands in front of a noun — on top of the comparative suffix -er itself. The comparative ending stacks: stem + -er (comparative) + weak or mixed ending, picked by the article and case. That is why der ältere Mann ends in -e but ein älterer Mann ends in -er — both are correct, and the rule is the same one that drives regular adjective declension.

Comparatives only take endings when they are attributive (before a noun). After sein, werden, bleiben — the predicative slot — the comparative stays bare: der Mann ist älter (no ending) vs. der ältere Mann (weak -e). The rest of this page walks through the full table, the irregulars (besser, höher, näher, mehr), and the mistakes B1 learners make most often.

German comparative endings at a glance

Compact view: comparative stem (schneller-, älter-, besser-) plus the ending demanded by the article and case.

The tricky part is stacking the comparative -er and the declension ending without losing one — so rehearse it in the free trainer further down. No sign-up is required, and it confirms every comparative form the instant you answer.

Use the table as a first lookup. The rest of the doc explains why each ending falls out and where the irregulars sit.

What are German comparative adjective endings?

Comparative adjective endings are the declension endings that attach to a comparative form (stem + -er) when it modifies a noun. They are not new endings — they are the same weak/mixed/strong endings used for any attributive adjective, only now stacked on top of an extra -er.

The build-up is layered:

• Step 1 — comparative suffix: schnell + -er = schneller (faster)
• Step 2 — declension ending: schneller + -e = schnellere (weak, after the definite article)

That gives der schnellere Zug — the comparative -er and the declension -e are both present. In the mixed pattern after ein, both surface separately as -er + -es: ein schnelleres Auto.

Crucially, the comparative suffix does not replace the declension ending. The two coexist, just like Lehrer (agent suffix -er) + plural -in does not collapse to a single morpheme.

When do comparatives take endings, and when not?

This is the line that trips up most B1 learners. The rule is purely positional:

• Attributive (before a noun) → take the comparative -er and an adjective ending.
• Predicative (after sein, werden, bleiben) → take only -er, no adjective ending.

Der Mann ist älter als sein Bruder. — The man is older than his brother. (predicative, no ending)

Der ältere Mann liest die Zeitung. — The older man reads the newspaper. (attributive, weak -e)

The same adjective, the same -er suffix; the position decides whether anything else attaches. This is identical to the predicative/attributive split for base adjectives, so once you have that rule, comparatives don't add a new principle — only an extra -er between stem and ending.

Comparative endings after definite articles (weak)

When the comparative follows der, die, das, dieser, jeder, jene, alle, beide, it takes weak endings — almost always -e or -en.

Der ältere Mann liest die Zeitung. — The older man reads the newspaper.

Ich nehme die billigere Variante. — I take the cheaper option.

Wir wohnen in dem größeren Haus. — We live in the larger house.

Die jüngeren Kinder spielen draußen. — The younger children play outside.

Comparative endings after ein/kein/mein(mixed)

After ein, eine, kein, keine, and the possessives (mein, dein, sein, ihr, unser, euer, Ihr), the comparative takes mixed endings. The ending carries the gender/case information that ein alone cannot mark (masculine and neuter nominative lack a signal on ein itself).

Er hat einen besseren Vorschlag. — He has a better suggestion.

Sie sucht eine günstigere Wohnung. — She is looking for a cheaper apartment.

Wir brauchen ein größeres Auto. — We need a bigger car.

Das ist ein wichtigerer Punkt. — That is a more important point.

Note the double -er in the masculine nominative: ein schnellerer Wagen. The first -er is the comparative suffix; the second is the mixed ending. It looks heavy but is the correct standard form.

Comparative endings without an article (strong)

When no article precedes (mass nouns, plurals, generic statements), the comparative carries the strong endings — the comparative -er plus the article-like ending that der/die/das would otherwise contribute.

Stärkerer Kaffee hilft am Morgen. — Stronger coffee helps in the morning.

Wir trinken kälteres Wasser. — We drink colder water.

Sie hat bessere Ideen als wir. — She has better ideas than us.

The endings match the article you would have used: der → -er, das → -es, die (fem./pl.) → -e/-e.

Superlative endings: attributive vs. am -sten

The superlative is the cousin of the comparative. Attributively, it almost always pairs with a definite article (or possessive), so it takes weak endings on top of the superlative suffix -(e)st.

Er ist der beste Spieler im Team. — He is the best player on the team.

Sie hat die höchste Note bekommen. — She got the highest grade.

Wir haben die teuersten Karten gekauft. — We bought the most expensive tickets.

Predicatively, the superlative uses the fixed adverbial form am + adj + -(e)sten with no adjective ending:

Dieses Auto ist am schnellsten. — This car is (the) fastest.

That am -sten form never declines — only the attributive superlative does. A small spelling note: adjectives ending in -d, -t, -s, -ß, -z, -sch slot an extra -e- in (kälteste, kürzeste, heißeste); groß is the exception with no -e- (größte).

Irregular comparatives: besser, höher, näher, mehr

A small set of high-frequency adjectives has irregular stems. They still decline normally — the irregularity is only in the stem.

hoch loses its -ch in the comparative (höher, not *höcher) but gets it back in the superlative (höchst-). nah shifts to nächst- in the superlative — the same form that doubles as the adverb "next".

The exception: mehr does not decline

Mehr is the only comparative that never carries endings. Treat it as a fixed quantifier:

Ich brauche mehr Geld. — I need more money.

Er hat mehr Erfahrung als ich. — He has more experience than I do.

Wir brauchen mehr Informationen. — We need more information.

Don't confuse mehr with mehrere ("several"). Mehrere is an indefinite quantifier and does decline: mehrere Leute, mit mehreren Ideen. They are different words.

Umlaut in comparative and superlative

Many one-syllable adjectives add an umlaut before the -er and -(e)st suffixes. The declension is unchanged — the umlaut sits inside the stem.

So der ältere Mann is alt → ält- (umlaut) + -er (comparative) + -e (weak). Three operations, one word.

Common pitfalls and how to avoid them

The most frequent comparative-declension errors learners produce, with corrections.

A useful self-check: build the word in two passes. First, write the comparative stem (älter, besser, schneller). Then ask which article precedes it and apply the same ending you would for regular adjective declension. The stacking is the whole story.

Comparatives and the rest of adjective grammar

Comparative endings reuse the patterns from other adjective topics — once you know one, the others follow:

• Base endings — the full weak/mixed table is in German adjective declension; comparatives just stack -er on top.
• No-article forms — when there is no article, see strong declension; the comparative -er sits before the strong ending.
• Nominalized comparatives — der Ältere (the older one), die Bessere (the better one) follow nominalized-adjective rules and capitalize.
• Participles as comparatives — ein interessanteres Buch, der schreiendere Ton behave like normal adjectives once formed; see participial adjectives.

In short: there is no separate "comparative declension table" to memorize. There is the comparative suffix -er, and there are the normal adjective endings — applied in that order.
