Okay, the user sent "re-used". Let me check the translation rules again. The first rule says to translate all content into Thai. The second rule states that if the content is already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "re-used" is in English. I need to translate it into Thai. The correct translation for "re-used" in Thai would be "ใช้ซ้ำ" (pronounced "chai sam"). Let me make sure there's no other possible translation. "Re-used" can mean something that has been used again, so "ใช้ซ้ำ" fits perfectly.
I should output just the translation without any extra text. The user emphasized that they want only the translation result. No explanations or other content. So, the response should be "ใช้ซ้ำ" and nothing else. Let me double-check if there's any chance the user might have intended a different context, but "re-used" is pretty straightforward. Alright, ready to send the translation.
