Underline the odd word.

A) The odd word is "this". Explanation: "red", "purple", and "green" are colors, while "this" is a demonstrative pronoun. B) The odd word is "that". Explanation: "what", "how", and "where" are interrogative words (question words), while "that" is a demonstrative pronoun. C) The odd word is "blue". Explanation: "five", "seven", and "one" are numbers, while "blue" is a color. D) The odd word is "magic". Explanation: "name", "old", and "great" are adjectives describing characteristics, while "magic" is a noun (or adjective, but "name", "old", "great" fit a different semantic category here). Actually, let's re-evaluate D: "magic" (noun/adj), "name" (noun), "old" (adj), "great" (adj). This one is tricky. Let's look again. Maybe it's about parts of speech. Wait, "name" is a noun, "magic" can be a noun or adjective. "old" and "great" are adjectives. Actually, looking at common school exercises: "magic", "name", "old", "great". Perhaps "name" is the odd one out as a noun? Or "magic"? Let's assume "name" is the odd one if others are adjectives, but "magic" can also be a noun. Let's provide the most logical categorization: Let's re-examine D: Magic (adjective/noun) Name (noun) Old (adjective) Great (adjective) Maybe the answer is "name" because it is a noun, while the others can function as adjectives? Or perhaps "magic" is the odd one. Let's stick to the clearest ones. Actually, let's correct D: magic (adjective), old (adjective), great (adjective) - "name" is a noun. So "name" is the odd one.
