What is an example of morphology in language?

Morphology in language refers to the study of the structure of words and how they are formed. It involves understanding the smallest units of meaning, known as morphemes, which may include roots, prefixes, and suffixes. When selecting the answer that exemplifies morphology, recognizing words that share a common root is particularly relevant. This involves the ability to identify and understand how variations of a word can relate to one another through a shared base or root form. For instance, the words "happy," "happiness," and "unhappily" all derive from the same root "hap," which relates to the concept of happiness.

The other options do not specifically pertain to morphology. Using polite phrases is more about pragmatics and social language skills. Recognizing valid English-like nonsense words relates to phonetics and phonology rather than the structural components of words. Structuring paragraphs focuses on text organization and writing skills, rather than the examination of word structure and formation. Therefore, identifying common roots in words is the most accurate representation of morphology.
