MANDARIN SENTENCE PATTERN
Describing with 很
Use an adjective as the main description of a subject.
Subject + 很 (hěn) + adjective
Many Mandarin adjectives can describe a subject directly. In a neutral statement 很 often links the subject and adjective without strongly emphasizing very.
Context and stress determine how strong 很 is. In a simple negative description, 不 can precede the adjective.
Examples
她很好。
She is well.
今天很热。
It is hot today.
这本书不贵。
This book is not expensive.
Keep in mind
The common pattern is 今天很热, without 是 before 很热.
