There are several ways to classify a prompt as intelligible or unintelligible:

1. Grammar and syntax: An intelligible prompt should follow grammatical and syntactical rules and make sense in the context of the language being used.

2. Coherence and structure: An intelligible prompt should have a clear structure and coherent flow of ideas, so that the meaning is easy to understand.

3. Vocabulary and semantics: An intelligible prompt should use appropriate vocabulary and convey a clear meaning through the words being used.

4. Context: An intelligible prompt should be relevant and meaningful in the context in which it is being presented.

If a prompt fails to meet any of these criteria, it may be classified as unintelligible.
