I need to process each word individually. Let's take a longer example. Suppose the input is: "The quick brown fox jumps over the lazy dog." All words are common except maybe none are proper nouns. The output would be something like "That fast brown vixen hops above those idle dog."
First, they mentioned that proper nouns shouldn't be changed. So I need to identify proper nouns in the text. Maybe names of people, places, or specific terms like company names. For example, if there's a name like "Apple", that shouldn't be altered. But if the word is "apple" as in the fruit, then I can replace it with alternatives. I need to process each word individually
Next, each word (except proper nouns) should be replaced by a set of three options. The format is important here: option2. I need to make sure that the structure is correct, no markdown, just plain text with curly braces and pipes. The output would be something like "That fast
I also need to ensure that the replacements are words that could fit grammatically in the original sentence. If the original word is an adjective, replacing it with other adjectives would be necessary. Similarly for nouns, verbs, etc. So grammatical category should match. For example, if there's a name like "Apple",
Wait, "into" twice here. Oops, should be "into|toward|to". Also, "into" might be incorrect for "to the supermarket". Maybe better: "went" could be replaced with "went|arrived|visited", "to" with "toward|into|into" but maybe not. Maybe "to" as "to|into|toward".
