Morphology is the study of the structure and form of words in a language. It deals with how words are formed, their component parts (called morphemes), and the rules governing the combination of these morphemes to create meaningful words. Morphemes can be roots, prefixes, suffixes, or infixes, and understanding their arrangement helps in understanding the meaning and grammatical properties of words. Morphology is an essential aspect of linguistics and plays a crucial role in language analysis and understanding.
