Potential issues include words with no valid synonyms. For example, "over" might be tricky. In such cases, using a thesaurus might help, but sometimes there are no direct synonyms. In that case, pick the closest possible alternatives even if the context might slightly change.

I should also check the length and structure of each replacement. Each set of variants should be in the specified format without any additional text. The user wants only the output text, so no explanations or extra details.

- "John" is a proper noun, skip. - "went" → departed - "to" → toward - "Paris" is a proper noun, skip. - "and" → also - "bought" → gotten - "a" → that - "new" → fresh - "book" → book - "for" → regarding - "school" → institution

Let me test this with an example. Suppose the input is "The quick brown fox jumps over the lazy dog." Proper nouns here are none, so all words are replaceable. For "quick", synonyms could be hasty. For "brown", maybe tan. "Fox" is a common noun, so alternatives could be lynx. "Jumps" as a verb might be hops. Continuing this process for each word.

I need to process each word one by one, check if it's a proper noun, and replace non-proper nouns with three variants. Let me outline the steps:

Another consideration is ensuring that the variants are valid in terms of part of speech. For instance, if the original word is a verb, the alternatives should also be verbs. If it's an adjective, the variants should be adjectives, and so on. This will maintain the grammatical correctness of the rewritten text.

I also need to be cautious with words that have multiple meanings. For example, "over" could have different synonyms depending on context: upon. It's important to choose variants that maintain the intended meaning.

Okay, the user wants me to rework each word in the text with three variants, using the format word2. They also mentioned to skip proper nouns and only output the text. Let me break this down.
