Wait, the user also specified "no changes to proper nouns." So I need to identify names like "NASA" or "Paris" and leave them as they are. For example, if the input is "NASA engineer," I should convert "engineer" to three synonyms but leave "NASA" unchanged. Hmm, but how do I detect proper nouns accurately? Maybe proper nouns are capitalized but that's not always reliable. Maybe I should look for any term that's a known proper noun. Since I can't look up online, I need to rely on my existing knowledge of common proper nouns.
Now, testing with the example given by the user:
But to avoid confusion, perhaps it's better to choose synonyms that match the part of speech. So for "love" as a noun, use nouns: fondness. For a verb, synonyms like adore. Let me make sure about this. Since the user provided an example with "care|admiration|fondness", maybe they included a verb in the first position. However, "care" here is a verb (care about something) while the others are nouns. That's inconsistent. Maybe it's a mistake, but I need to follow the user's examples. So perhaps in their case, they don't mind as long as the words are related in meaning. Therefore, perhaps the main focus is on synonymy, regardless of part of speech. However, in practical use, changing the part of speech could alter the grammatical structure of the sentence. Since the user wants the output for conversion, it's crucial to maintain the correctness.

But how to find synonyms? For each term, generate three synonyms. Maybe using a thesaurus approach. For example, for "love", synonyms are "affection", "care", "adoration", "fondness", etc. Choose three. However, some words might have fewer synonyms. For such cases, maybe use near-synonyms or collocations. Also, need to avoid hyphenated words unless necessary.
So, steps:
First, I need to parse each term in the input. For each term, I have to check if it's a proper noun. If it's not, I need to find three synonyms. The challenge is ensuring that the synonyms are accurate and appropriate. I should avoid using hyphenated words or phrases unless they're necessary. Also, the output must strictly follow the syn3 format without any markdown.
