The types of ambiguity in modern Chinese include the following: 1. Ambiguity: Ambiguity refers to the fact that the same word can be used differently in different context, causing ambiguity. For example, the word "this" could mean "this" sound,"this" person,"this" direction, etc. 2. Polysemy: Polysemy refers to the fact that the same word can have different meanings in different context, causing ambiguity. For example, the word "computer" could mean computer, computer hardware, computer software, and so on. 3. Ambiguity due to improper matching: improper matching refers to the ambiguity caused by the improper matching of other words with the same word. For example, the words "like" and "eat" could mean "like to eat" or "don't like to eat". 4. Ambiguity: Ambiguity refers to the existence of ambiguity in the meaning of the same word. For example, the ambiguous meanings of "live" and "live" could mean "a person is still alive" or "a person has lived his whole life". The methods to differentiate them included: 1. Comparing the context: By comparing the meaning of the word in different context, you can determine whether the word is ambiguous. 2. Check the dictionary: Check the relevant dictionary to understand the exact meaning of the word to determine whether the word is ambiguous. 3. Understand the context: By understanding the meaning of the word in the context, you can determine whether the word is ambiguous. These are the types of ambiguity in modern Chinese. When reading or writing, we need to pay attention to the accuracy of the words used to avoid ambiguity.
