A morpheme is the smallest meaningful linguistic unit in a language, distinguished from other morphemes by its semantic or grammatical function. Morphemes cannot be broken down into smaller meaningful parts without losing their linguistic significance. They serve as the building blocks of words, combining to form lexemes (word forms) and conveying meaning through their arrangement and inflection.

Morphemes are categorized into two primary types: free morphemes and bound morphemes. Free morphemes can stand alone as independent words, such as "cat," "run," or "happy." Bound morphemes, on the other hand, cannot function alone and must attach to other morphemes to form words. Examples include prefixes like "un-" (as in "unhappy") and suffixes like "-ing" (as in "running"). Some morphemes, known as affixes, modify the meaning or grammatical role of the root morpheme they attach to.

Morphemes play a crucial role in morphology, the study of word formation and structure. They enable languages to express complex ideas through word derivation and inflection. For instance, the English word "unhappiness" consists of three morphemes: "un-," "happy," and "-ness," each contributing to the overall meaning. Similarly, inflectional morphemes, such as "-s" in "cats," indicate grammatical features like plurality.

The analysis of morphemes is essential in linguistics for understanding how languages encode meaning and structure. By examining morphemes, linguists can explore patterns of word formation, grammatical relationships, and semantic distinctions across languages. This study also aids in the development of computational linguistics tools, such as natural language processing systems, which rely on morpheme-based analysis for tasks like text segmentation and machine translation.
