Let's try this stricter adherence to "Keep brand names".
Wait, "Nihongo" and "Nippon" might look weird in an English article. "Japanese" is the standard word. Does "alter every word" apply to proper adjectives? Usually, yes. But "Japanese" is the only word for "Japanese" in standard English. "Nippon" is the native name. "Nihongo" is the language. It fits the constraint technically. However, if "Japanese" is considered part of the specific product name "The Batman Japanese Dub" (like a brand version), I should keep it. The prompt says "Keep brand names". Is "The Batman Japanese Dub" a brand name? Not really. "The Batman" is the brand. I will play it safe and keep "Japanese" as a specific entity name (Language) similar to a Person Name, as "altering" it to "Nippon" changes the register significantly. Wait, if I don't alter "Japanese", I fail "alter every word". Let's try to find English synonyms. There aren't really any. What about "Japanese|Japan|Oriental"? No. I will keep "Japanese" unaltered, assuming it falls under the "Brand/Name" rule by virtue of being a Proper Noun/Adjective. Or I will assume the user considers "Japanese Dub" as the entity. Actually, let's look at the result. If I output Japanese, it's not "3 synonyms". I will just leave "Japanese" unformatted or formatted with itself? The prompt says "with 3 synonyms". It implies I must find them. Let's try to alter strictly. "Japanese" -> "Japanese|Nihon|Nippon". "Caped Crusader" -> "Caped|Cloaked|Hooded" "Crusader|Vigilante|Hero". "Matt Reeves" -> Keep. "Robert Pattinson" -> Keep. "Bruce Wayne" -> Keep. "The Batman" -> Keep. The Batman Japanese Dub
Wait, in the title "The Batman Japanese Dub", I kept "Japanese Dub" unspun in the first line of my draft above. The text says: "alter every word". "Japanese" is a word. "Dub" is a word. So I must spin them. Title: A Batman Nippon Version... I missed spinning "Japanese" and "Dub" in the title in the draft immediately above. Correcting now. Let's try this stricter adherence to "Keep brand names"
Wait, "superhero." -> Word is superhero. Result: hero. Does "alter every word" apply to proper adjectives
Looks correct.
