does this sentence contain an unclear antecedent?

In the encyclopedia, it says that English has words from many different languages.

To determine if the given sentence contains an unclear antecedent, we need to identify if there is any ambiguity or confusion regarding the pronoun or noun that the pronoun refers to. In this case, the pronoun "it" is used to refer to "the encyclopedia."

To verify if the antecedent is unclear, we should look for any uncertainty about which specific encyclopedia the sentence is referring to. If there is only one encyclopedia being discussed in the context, then the antecedent is clear, and there is no ambiguity.

However, if multiple encyclopedias are mentioned, or if there is more than one possible encyclopedia that the sentence could be referring to, then the antecedent might be considered unclear.

Since we are not provided with any additional context, it is difficult to determine if there is an unclear antecedent in this sentence. If there is only one encyclopedia being discussed, the antecedent is clear. If there are multiple encyclopedias or if the context is ambiguous, then the antecedent could be unclear.

To clarify the antecedent in the sentence, you would need to provide more context or information about the specific encyclopedia being mentioned.
