Verified step by step guidance

1. Understand the concept of 'intonation' in linguistics: Intonation refers to the variation of pitch while speaking, which can affect the meaning of a word or sentence.
2. Recognize that in some languages, intonation is crucial for distinguishing between different meanings of the same word. This is particularly true in tonal languages where pitch changes can alter word meaning.
3. Differentiate between the given options: 'morphemes' are the smallest units of meaning in a language, 'phonemes' are the smallest units of sound, and 'syntax' refers to the arrangement of words and phrases to create sentences.
4. Identify that the question is asking about a feature that changes the meaning of a spoken word, which aligns with the concept of intonation rather than morphemes, phonemes, or syntax.
5. Conclude that the correct answer is 'intonation' because it directly relates to how the pitch or tone of a spoken word can change its meaning in certain languages.
