Word structure rewards close inspection. Morphology is the study of the internal structure of words and of 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 isolating, agglutinative, and fusional strategies.

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