Word structure rewards close inspection. Morphology is the study of the internal structure of words and the rules by which words are formed and inflected.

The field covers inflection, derivation, compounding, and other word-formation processes. Morphologists analyze paradigms, allomorphy, and the interface between form and meaning. Cross-linguistic comparison reveals strategies ranging from isolating to agglutinative and fusional systems.

Morphological knowledge supports literacy, vocabulary growth, and natural language processing. Theoretical debates address whether morphology is an autonomous component or reducible to syntax and phonology. Practical description of any under-documented language always includes a morphology sketch.
