herd: [OE] Herd is part of a widespread Indo- European family of words denoting ‘group’ (others include Sanskrit çárdhas ‘troop, multitude’ and Welsh cordd ‘tribe, family’). It goes back to an Indo-European *kherdhā-, whose Germanic descendant *kherthō produced German herde, Swedish and Danish hjord, and English herd. Herd ‘herdsman’, now found only in compounds such as shepherd and goatherd, is a different word, albeit derived from the same Germanic source. Its Germanic relatives are German hirte, Swedish herde, and Danish hyrde.
