Morphology is the branch of linguistics that focuses on the structure of words. It examines how words are formed, including the analysis of roots, prefixes, suffixes, and how these components come together to create different meanings or forms of a word. This includes the understanding of inflection (changes in form to express different grammatical features) and derivation (the process of creating new words). By studying morphology, one gains insight into the rules governing word formation and the internal structure of words, which is essential for understanding language at a deeper level.

The other options touch on different areas of linguistics. The sound of words and phrases relates to phonetics and phonology. The meaning of sentences pertains to semantics.
