What is the difference between maybe and maybe, meaning and usage, etc., in Chinese as a foreign language.

Both can express possibility: He may come. He might come. There are three differences here. (1) When adding verbs to express possibility, "maybe" is an auxiliary verb and "maybe" is an adverb; (2) "Maybe" is more colloquial. (3) "Maybe" means pure speculation, while "maybe" means unexpected, that is, I didn't expect him to come or didn't want him to come, but now this possibility has appeared. Another example: the weather forecast says it won't rain today, but it suddenly gets dark, so you will say "it might rain." The expression is contrary to what was originally expected. If you say "It may rain", it simply means that there is a possibility of rain.

"Maybe" can be used as a noun, such as "There is a possibility of rain" in the above sentence; "Maybe" cannot be used as a noun.

"Maybe" can be used as an adjective, such as "very likely" and "this is possible"; "maybe" cannot be used as an adjective.

"Maybe" can be used as a verb, such as "This matter is still uncertain"; "maybe" cannot be used as a verb.

When teaching, there is no need to emphasize the difference in parts of speech. You can summarize the structure. Just explain clearly the differences in structure, usage, and context.
