Adjectives state how something is. German elementary school children call them "Wie-Wörter", because they are schooled to ask "How is or are [so and so]?". Predicative adjectives state and describe an object while not coming right in front of the noun. They are easier for you, because you will neither have to include information about the gender nor the number in this adjectives. What? Look: "Der Mann ist schön; die Frau ist schön; das Kind ist schön". "Schön" is the same in all phrases. Easy! Later, however, you will learn how to conjugate (i.e. modify) the adverb to suit the noun, e.g. "ein dicker Mann" but "ein dickes Kind".
Very good to know! By the way, you say 'adverb' in your last sentence there, when I believe you meant adjective. If you didn't, I apologise!
Thanks for the tips! I did want to mention that adjectives are "declined" rather than "conjugated."
thanks for the answer, i've already put a question bellow about what's the purpose of this lesson. now it's clear thanks.
