How does 比 work in this sentence?

比 is the basic comparison word in Mandarin.

The pattern is:

A 比 B + adjective

So here:

秋天 比 春天 凉快一点儿
= Autumn is a little cooler than spring

• A = 秋天
• B = 春天
• adjective = 凉快

A very important point: unlike English, Mandarin does not use a separate word like more here. The comparison is already expressed by 比.

Why is the sentence 秋天比春天凉快一点儿 and not 秋天比春天很凉快?

With 比, you normally put the adjective directly after the comparison:

A 比 B + adjective

So:

• 秋天比春天凉快一点儿 = natural
• 秋天比春天很凉快 = unnatural in standard usage

The word 很 is often used in simple descriptive sentences like:

• 秋天很凉快 = Autumn is cool

But after 比, 很 is generally not used that way.
