Using adjectives, adverbs, comparisons and superlatives accurately will enhance both your writing and speaking. Mastering them successfully helps you to use descriptive language in a variety of ways.
A superlative adjective describes the 'best' or 'most' form of an adjective, eg: the brightest, prettiest, smartest, most wonderful, etc.
Er ist der schnellste Läufer der Gruppe. – He is the quickest runner in the group.
Ihre Oma ist die langsamste Autofahrerin. – Her granny is the slowest driver.
How to form superlative adjectives
Take an adjective or adverb > schön (beautiful).
Add -ste to the end > schönste (most beautiful). Or add -este if there is a -t or -d on the end of the adjective – leicht > leichteste (easiest), hart > härteste (hardest).
If there is a noun add der, die or das (the) > Tobias ist der lustigste Junge. (Tobias is the funniest boy).
If you want to use a superlative adjective where there is no noun, add am -sten > Iris ist am fleißigsten. (Iris is the most hard-working).
Das Billige ist immer das Teuerste - Penny wise, pound foolish (literally: the cheapest is always the most expensive)
