grandchildren

The word "grandchildren" is a transparent compound formed within English. The prefix "grand," borrowed from French and ultimately from Latin grandis, meaning "great" or "large," was adopted in the 13th century to denote a generational step in kinship terms, such as "grandfather" (a father on a greater scale). It is combined with the native English word "children," the plural of "child," which traces back to Old English cild. The compound logic is direct: "grandchildren" are the "great" or "one-generation-removed children" of a person. This pattern of using "grand-" to indicate a lineage one degree further removed became a standard and productive method in English for describing familial relationships across generations.

Structure: grand (great) + children (offspring) - grand: From Latin grandis (great, large, full-grown). In English, it functions as a prefix indicating a family relationship one generation removed. - children: From Old English cild (child, infant) with the plural suffix -ren. It functions as the base noun denoting offspring.
