Komparativ & Superlativ — more and most

Comparatives and superlatives in German are lighter than English. You just add a suffix — no extra "more" needed for long words, no "the most" for superlatives. One rule: shorter adjectives add an umlaut on the way up.

The two forms

Umlaut, spelling fixes, and irregulars — all in one matrix

Most one-syllable adjectives with a, o, u add an umlaut. Adjectives ending in -d, -t, -s, -ß, -z, -sch need an extra -e- before -sten. And there's a small handful that go rogue and just need to be memorized. The matrix below shows all four groups side by side with each ending color-coded.

Multi-syllable adjectives (interessant, wichtig) and any that naturally end in umlautable vowels don't take the umlaut: interessanter, am interessantesten. mehr and viel are the irregular pair that native speakers use constantly — lock them in.

Comparing two things: als

"Than" in German is als. Never wie (that's for "equal to" comparisons).

For "as X as" comparisons (equals): so ... wie ....

Superlatives in the real world

Predicate superlative — am -sten. Use this when the superlative comes after sein or acts like an adverb.

Attributive superlative — der/die/das -ste. Use this when the superlative sits between an article and a noun, and decline it like any other adjective.

The -est insertion for pronounceability

If the adjective stem ends in -t, -d, -s, -ß, -z, or hisses, you slip an -e- before the superlative ending so it doesn't collide:

• alt → am ältesten (not ältsten)
• kalt → am kältesten
• heiß → am heißesten
• kurz → am kürzesten

Same phonetic rule you've now seen in present tense, Präteritum, and participles.

Common mistakes, named

1. Using wie for "than." Er ist größer wie ich. ❌ → Er ist größer als ich. ✓ (Very common error, even among native speakers — but non-standard.)

2. Adding mehr before a German adjective. mehr intelligent ❌ → intelligenter ✓ German doesn't stack "more" + adjective. It's a suffix.

3. Leaving off the am in predicate superlatives. Der Zug ist schnellsten. ❌ → Der Zug ist am schnellsten. ✓

4. Forgetting to decline the attributive superlative. Der schnellst Zug. ❌ → Der schnellste Zug. ✓ Superlatives are adjectives — they take adjective endings.

Where this leads

A quick pivot back to pronouns for a stretch — starting with the reflexives (mich, dich, sich), which you need for a huge family of everyday verbs like sich freuen and sich erinnern.

Next up: Reflexivpronomen — mich, dich, sich.
