形容词的词序是什么？

There are two tests you can use to identify whether an adjective is cumulative or coordinative.

Test 1: The "and" test

For the first test, try putting the word "and" between the adjectives. Using the word "and" suggests the adjectives have equal importance. This would make them coordinative, not cumulative.

Let's try it with "new folding bike." Does "new and folding bike" have the same meaning as "new folding bike"? Not so much. So, we know they are cumulative, not coordinative.

Test 2: Change the order

For the second test, change the order of the adjectives and decide whether the meaning changes. For example, "Folding new bike" does change the meaning. So we must keep the original order and these are cumulative adjectives.

Punctuation

We also punctuate cumulative and coordinative adjectives differently.

We do not put commas between cumulative adjectives nor do we put "and" between them, as in today's many examples.

We do put commas between coordinative adjectives and we can use the word "and," as in "loud, hot and crowded Metro."
