Okay, the user wants me to translate "full-length word" into Thai. Let me check the rules again. The first rule says to translate all content into Thai. The second rule says if it's already in Thai, leave it as is. The third rule is to provide only the translation without explanations.
So, "full-length word" isn't in Thai. I need to translate it. The term "full-length" can be translated as "เต็มความยาว" and "word" is "คำ". So putting it together, it would be "คำที่มีความยาวเต็มที่". Wait, but maybe there's a more natural way to say it. Let me think. Sometimes "full-length" in context might be better translated as "เต็มความยาว" or "ยาวทั้งหมด". But "คำที่มีความยาวเต็มที่" seems correct. Alternatively, "คำที่ยาวเต็มที่" might be more concise. Hmm, but I should stick to the direct translation unless there's a common phrase. Since the user didn't provide context, I'll go with the direct translation. So the answer is "คำที่มีความยาวเต็มที่".
