So in my case, for each word in the user's text, I'll generate three synonyms, which may include the original word, as in the example. For instance, "psychological" becomes psychological. So including the original as one of the three. Therefore, even if the original word is part of the trio, it's acceptable.

"Several" → "numerous|multiple|a variety of". "Key figures" → "important members|leading members|prominent individuals". "Emerging" → "arose|began|surfaced". "Unique" → "distinct|individual|unique".

But wait, some of these synonyms might change the meaning. For example, "European literature" is specific, but "continental poetry" might be too narrow. However, the user wants synonyms regardless, so I have to proceed.
