Comparison is one of the few areas of German grammar that is simpler than its English equivalent, which makes it a good place to build confidence. The endings are mechanical. What has to be learned by exposure is narrow: the dozen or so common adjectives that add an umlaut, and the five irregulars that change shape entirely.
Steigerung contains 221 questions across A1 to B2, each written for the adjective it drills rather than dropped into a generic frame. The A1 tier is deliberately narrow, covering only gut, viel and gern — the three comparison forms that appear in the Goethe A1 word list as ordinary vocabulary rather than as a grammatical pattern. Comparison as a system starts at A2, which is where the word lists introduce it.
Comparative and superlative are drilled together in one mixed pool, because in real use you never know which one a sentence will need. All forms are computed from the rules, with the irregulars listed explicitly, so the app cannot produce a form that does not exist. Superlatives are accepted with or without the leading am.
The most common error at this level is not a form at all but a word: comparison uses als, not wie. Größer als means bigger than; so groß wie means as big as. The two are not interchangeable.
German makes comparisons more regularly than English does. Where English switches between bigger and more interesting depending on the length of the word, German simply adds an ending to everything — even to long adjectives. interessanter, not mehr interessant.
| form | how | example |
|---|---|---|
| Positiv | the plain adjective | klein |
| Komparativ | + -er | kleiner |
| Superlativ | am + -sten | am kleinsten |
Mein Zimmer ist kleiner als deins.
Von allen Zimmern ist dieses am kleinsten.
A set of common one-syllable adjectives add an umlaut as well as the ending. There is no way to predict which ones — but the list is short and the words are frequent, so exposure handles most of it.
| adjective | Komparativ | Superlativ | meaning |
|---|---|---|---|
| alt | älter | am ältesten | old |
| jung | jünger | am jüngsten | young |
| lang | länger | am längsten | long |
| kurz | kürzer | am kürzesten | short |
| warm | wärmer | am wärmsten | warm |
| kalt | kälter | am kältesten | cold |
| stark | stärker | am stärksten | strong |
| groß | größer | am größten | big |
Also in this group: arm, dumm, hart, klug, krank, scharf, schwach, schwarz, gesund.
Note that the umlaut only appears in the comparative and superlative. The plain adjective keeps its original vowel: alt, not ält.
These change more than their ending, and they are among the most-used words in the language — worth learning as a single block on day one.
| adjective | Komparativ | Superlativ | meaning |
|---|---|---|---|
| gut | besser | am besten | good |
| viel | mehr | am meisten | much / many |
| gern | lieber | am liebsten | gladly |
| hoch | höher | am höchsten | high |
| nah | näher | am nächsten | near |
hoch loses its c before an ending — höher, never hocher — and groß takes am größten rather than the expected am größesten.
gern is worth special attention because it works with verbs rather than nouns: Ich trinke gern Kaffee → Ich trinke lieber Tee → Am liebsten trinke ich Wasser. That progression is how you express preference in everyday German.
The superlative usually adds -sten. But if the adjective ends in -d, -t, -s, -ß, -z, -x or -sch, an extra e slips in to make the word pronounceable. Adjectives ending in a vowel do the same: neu → am neuesten.
laut → am lautesten
kalt → am kältesten
interessant → am interessantesten
heiß → am heißesten
Say am lautsten out loud and the reason becomes obvious.
The one exception: groß ends in ß but takes am größten, not am größesten. It is the only common adjective that breaks this rule, so learn it as a one-off.
| adjective | Komparativ | note |
|---|---|---|
| teuer | teurer | the -er loses its e |
| dunkel | dunkler | the -el loses its e |
| leise | leiser | already ends in -e, so only -r is added |
| sauber | sauberer | keeps its e — only teuer drops it |
A comparative used in front of a noun declines like any other adjective, so it carries two endings at once — the comparative -er and then the case ending.
ein größeres Zimmer · mit dem älteren Bruder · die bessere Lösung
The superlative behaves the same way and drops the am: das größte Zimmer, der beste Film.
| level | focus |
|---|---|
| A1 | gut → besser, viel → mehr, gern → lieber as vocabulary |
| A2 | the -er and am …-sten pattern as a system, the umlaut group |
| B1 | the remaining irregulars, the -esten rule, comparatives before nouns |
| B2 | longer adjectives and comparative forms in formal writing |
