Which field studies how words are formed from smaller elements?

The correct answer is Morphology, which is the field of study that focuses on the structure of words and how they are formed from smaller units called morphemes. Morphemes can be prefixes, suffixes, or root words and serve as the building blocks of language. Understanding morphology allows us to analyze how different morphemes combine to create new meanings and to signify different grammatical functions, such as tense or plurality.

This field is crucial in the study of language development and disorders, as it helps to explain how children acquire language and how certain language impairments may manifest in their ability to form and manipulate words. By studying morphology, researchers and practitioners can better understand the complexities of language and support individuals who may struggle with word formation and usage.
