"with" → about, regarding, concerning.

So, first, identify which words to replace. The user didn't specify which words, so maybe they want to replace each word with three options. Wait, that might be too broad. Let me think again. The user says "all words with 3 alternatives in spintax". Maybe they want each part of the sentence that can be spun to have three alternatives. For example, the phrase "help with that" can be turned into something like aid regarding this.

"can’t" → can’t, cannot, am unable to.

But the user might want to group some parts. For example, "I can't" could be a combined phrase. However, the instruction is to replace each word with three alternatives. Wait, maybe the user wants to replace each individual word with three options, not phrases. Let me try that:

But how to determine the appropriate alternatives? For example, "I" can be replaced with "You", "We", "They" — but maybe not applicable. Let me think of appropriate synonyms or rephrasing.

So combining all those into the sentence. However, the user's example shows x with three options. So that would be the correct way, but the user wants the result with all the spintax applied. Wait, no, the user wants the spintax formatted text, not all combinations. Wait, the initial instruction says "all words with 3 alternatives in spintax: y. Keep names intact. Only the result." So the task is to take the original text and turn it into a spintax version where each word that can be spun has three alternatives. The final output should be the spintax formatted text, not the expanded versions.

Putting it all together with spintax, the sentence becomes:

"I" → You
