Correct Response: B. Syntax is the way in which words are put together to form phrases. In English, word order helps reveal the relationships among words. In this case, changing the position of the word only in a sentence changes the meaning of the sentence, even though all of the other words in the sentence stay in the same order. Semantics (A) is the study of the meanings of individual words, phonology (C) is the study of speech sounds, and lexicon (D) is the vocabulary of a language.
