Let me think. If I were to process a sentence, say "The quick brown fox jumps over the lazy dog", I would replace each word with three synonyms. For "quick", synonyms might be rapid, swift, fast. So it becomes It swift tan fox... and so on. Proper nouns like "Fox" in a name would stay. But in the example, there are no proper nouns.
Wait, the user said "rework every word with 3 synonyms in spintax: y. Proper nouns stay. Only output text." So they probably want me to take some input text, but since there's no input given, maybe they just want me to create an example. But the example they provided is "y". Hmm.

But the user might not have provided a specific text. So perhaps they want me to explain the process or give an example. Since the user says "Only output text," maybe they want an example of how the spintax looks. Let me create a sample sentence and apply the spintax to it. Let me think
For "on", synonyms could be "above", "upon", or "over". "Under" would be opposite. So "on|above|upon". That's acceptable. So it becomes It swift tan fox
So the example is It feline seated above those rug
Original sentence: "The cat sat on the mat."
