In contrast to English, is it possible to describe a Subjective with an Adjective without using a noun.
If you would like to say for example you are cute, you don’t say in Mandarin nĭ shì kěài你是可爱， but you say nĭ hěn kěài你很可爱。So you would say: ‘You very cute’
Eventhough hěn(很) means very, you use it for most neutral situations.
If you would like to express that you think that something is above the normal you use the word fēicháng（非常)。 So if you would like to say you are extremly cute it would be nĭ fēicháng kěài 你非常可爱
If something is negative, for example you are not cute, you use bù (不). Bù is also used to show that many nouns are a negative action. This is offer explain in more detailed in a different post. To say you are not cute in mandarin is so nĭ bù kěài你不可爱.
