The usage and difference between sick and ill are as follows.

I can answer this question. Although my spoken English is not very good, I am familiar with the vocabulary of CET4 and CET6. I have summarized a table for you to have a rough look at first:

Similarity: * * means "sick"

Difference: ill can only be used as a predicative, while sick can be used as both a predicative and an attributive.

Usage difference

Sick is mainly used in America. When it is used to explain "disease", it can be used as both predicative and attributive. In Britain, sick is predicative, meaning "nausea and vomiting" rather than getting sick.

Ill is commonly used in Britain. When you are sick, it is usually used as a predicative, not an attribute. In the United States, ill can be used interchangeably with sick when used as a predicative.
