Which aspect of language pertains to how sounds are organized and used?

Phonology is the correct choice because it specifically deals with the organization and use of sounds in a language. This includes the study of how phonemes, which are the smallest units of sound, are combined to create words and convey meaning. Phonology examines the rules governing sound patterns, including aspects such as intonation, stress, and rhythm. This foundational understanding is crucial for developing skills in reading and language, as it helps learners recognize the sounds associated with different letters and words.

In contrast, syntax refers to the rules and principles that govern the structure of sentences, focusing on how words combine to create meaning at the sentence level. Pragmatics involves the context-dependent aspects of language use, emphasizing how language is used in social situations and how meaning can change based on context. Morphology pertains to the structure of words and how they are formed from smaller units of meaning, but does not deal directly with how sounds are organized.
