Chinese doesn’t need a separate verb like “to be” before adjectives used as predicates.
- Pattern: Subject + adjective works like “Subject is adjective” in English.
- So 天气很冷 literally is “weather very cold”, but functions as “The weather is very cold.”
You normally do not say 天气是很冷 in simple descriptive sentences.
是 is usually not used directly before a descriptive adjective unless you’re contrasting or emphasizing something special (e.g. 天气是很冷,可是… “The weather is very cold, but…”).
Not always. In this kind of sentence:
天气很冷
很 is often acting as a linking word between the subject and an adjective, and its degree (“very”) is often weak or even almost neutral.
- You must not normally say 天气冷 as a standalone general statement; it sounds incomplete or too abrupt in neutral narration.
- So 很 is often needed to make the sentence feel natural, even if you don’t really mean “very”.
Depending on tone and context:
- Neutral: 天气很冷 ≈ “The weather is cold.”
- Emphatic: said with strong emphasis, it can mean “The weather is very cold.”
