What is the smallest unit of human sound that is recognizable but not classified?

• A. Phone
• B. Phoneme
• C. Morpheme
• D. Allophone

Answer: (A)

Think in terms of raw sound versus linguistic categories. A phone is the actual spoken sound you hear—the concrete acoustic event. It’s recognizable as a sound, but it isn’t yet tied to a specific linguistic function or distinction within a language. That makes it the smallest unit that is merely a sound without being classified as phonemic or morphemic. In contrast, a phoneme is an abstract unit that can change meaning in a language, so it’s a way of organizing sounds for contrast. A morpheme is the smallest unit with meaning. An allophone is a phoneme’s contextual variation that doesn’t change meaning. So the correct choice is the raw, unclassified sound: a phone.
