Celtic names originate from the languages and cultures of the Celtic peoples, primarily found in regions like Ireland, Scotland, Wales, and Brittany. These names often have deep meanings related to nature, history, or mythology, reflecting the rich heritage of the Celtic tradition. Common elements in Celtic names include prefixes like "Mac" (meaning son) and "O'" (meaning descendant of), which indicate lineage. Many Celtic names are still popular today, such as Siobhan and Liam in Ireland, or Ewan and Fiona in Scotland. These names often carry unique spellings and pronunciations, making them distinct from names in other cultures. The revival of interest in Celtic heritage has led to a renewed appreciation for these traditional names.
