Morphology, the study of the structure and formation of words, plays a crucial role in understanding how language functions. At the heart of this linguistic exploration lies the concept of morphemes, the smallest units of meaning in a language.
They can be classified into two main types: free morphemes and bound morphemes. Free morphemes can stand alone as meaningful words, such as "cat" or "run." On the other hand, bound morphemes are those that must attach to a free morpheme to convey meaning. Examples include prefixes, like "un-" in "undo," and suffixes, like "-ed" in "walked."
Inflectional vs. Derivational Morphemes:
Morphemes further classify into inflectional and derivational categories. Inflectional morphemes modify a word's grammatical meaning, often indicating tense, number, or gender. In English, the plural "-s" or the past tense "-ed" are examples of inflectional morphemes. Derivational morphemes, on the other hand, alter a word's meaning or part of speech. For instance, adding the derivational suffix "-er" to "teach" transforms it into "teacher."
