granddaughter

The word 'granddaughter' is a transparent compound formed within English by combining the native English word 'daughter' with the borrowed prefix 'grand'. The term 'daughter' has a deep lineage, tracing back to the Proto-Indo-European root for this fundamental kinship term. The prefix 'grand', entering English from French and ultimately Latin, was adopted in the 13th century to denote a degree of removal in familial descent, literally meaning 'great'. Thus, the compound's logic is direct: a 'granddaughter' is literally a 'great daughter', specifying the female child of one's own child, extending the family line by one generation.

Structure: grand (great) + daughter (female child) - grand: From Old French 'grant', 'grand', meaning 'great, large, tall', from Latin 'grandis' (full-grown, great, large). In English, used as a prefix to indicate a family relationship one generation removed. - daughter: From Old English 'dohtor', meaning 'female child', from Proto-Germanic 'duhtēr', ultimately from Proto-Indo-European 'dʰugh₂tḗr'.
