There are three adjective degrees in German:
This is the unmodified adjective.
Ich bin müde
I am tired
The comparative of equality and inferiority is formed with the positive degree:
Clauses of equality are formed with this construction:
so + POSITIVE ADJECTIVE + wie
Peter ist so dünn wie Tomas
Peter is as thin as Tomas
or with the construction:
gleich + POSITIVE ADJECTIVE + wie
Peter ist gleich ungelenk wie Tomas
Peter is as clumsy as Tomas
A very common usage is for comparing quantities of something. The structure is:
so + viel + NON-COUNT NOUN + wie /
so + viele + COUNT NOUN + wie
Ich habe so viel Geld wie du
I have as much money as you
Ich habe so viele Autos wie du
I have as many cars as you
The comparative of inferiority's structure is:
nicht so + POSITIVE ADJECTIVE + wie
Du bist nicht so intelligent wie ich
You're not as intelligent as me
The comparative degree is for constructing the comparative of superiority.
The comparative grade is formed generally by adding "er" to the adjective:
intelligent ➜ intelligenter
intelligent ➜ more intelligent
The comparative of superiority is formed with the construction:
ADJECTIVE IN COMPARATIVE DEGREE + als
Er ist stärker als ich
He is stronger than me
Peter ist dünner als Tomas
Peter is thinner than Tomas
müde ➜ müder
tired ➜ more tired
feige ➜ feiger
cowardly ➜ more cowardly
teuer ➜ teurer
expensive ➜ more expensive
dunkel ➜ dunkler
dark ➜ darker
lecker ➜ leckerer / leckrer
delicious➜ more delicious
sauber ➜ sauberer / saubrer
clean ➜ cleaner
krank ➜ kränker
sick ➜ sicker
The comparative of inferiority is formed with the construction:
weniger + ADJECTIVE + als
Er ist weniger intelligent als ich
He is less intelligent than me
Welches Auto ist am billigsten?
Which car is the cheapest?
krank ➜ am kränksten
sick ➜ sickest
seriös ➜ am seriösesten
serious ➜ the most serious
süß ➜ am süßesten
sweet ➜ the sweetest
There are some exceptions as in:
dringend ➜ am dringendsten
urgent ➜ the most urgent
neidisch ➜ am neidischsten
jealous ➜ the most jealous
groß ➜ am größten
tall ➜ the tallest
A frequent concern is about when to use am in the superlative and when not to. If the adjective is accompanied by a noun (the attributive form) am is not used.
Example:
Tata Nano ist das billigste Auto der Welt
Tata Nano is the cheapest car in the world
The following adjectives form the comparative and superlative irregularly:
Adjective | Comparative | Superlative | Meaning |
gut | besser | am besten | good, better, the best |
viel | mehr | am meisten | much, more, the most |
gern | lieber | am liebsten | gladly, preferably, most preferably |
hoch | höher | am höchsten | high, higher, highest |
nahe | näher | am nächsten | near, nearer, nearest |
An additional explanation. "Wie" will be used for the comparative of equality, while "als" will be used for the comparative of superiority.
