Several Celtic words have survived in modern English, particularly in place names and certain everyday vocabulary. Examples include "druid," "whiskey" (from the Irish "uisce beatha"), and "galore" (from the Irish "go leor"). Additionally, many place names in the British Isles, such as "Avon" (meaning river) and "Kent" (from a Celtic word meaning "headland"), also reflect Celtic origins. These remnants illustrate the lasting influence of Celtic languages on English.
