Strip away the affixes and a core remains. A root is the basic morpheme of a word that carries the principal lexical meaning and cannot be analyzed into smaller meaningful parts.

Roots combine with affixes to build stems and full words. In some languages roots have canonical shapes, such as consonant skeletons in Semitic morphology. Identifying roots is essential for dictionary organization and morphological parsing.

Historical linguistics reconstructs ancestral roots to compare related languages. Folk analysis sometimes misidentifies roots, producing misleading explanations. Accurate root segmentation supports scholarly description and practical vocabulary teaching.

• Core morpheme carrying basic lexical meaning
• Cannot be divided into smaller meaningful units
• Combines with affixes to form complex words
• Central to morphological and historical analysis
