What does celt mean?
A Celt is a member of the group of ancient Indo-European peoples who spoke Celtic languages and spread across much of Europe during the first millennium BCE, leaving lasting cultural footprints from Ireland to Iberia and Anatolia. The term covers diverse tribes — including those the Romans encountered in Gaul and Britain — united by shared language families rather than political unity. Modern descendants of their languages survive as Irish, Scottish Gaelic, Welsh, Cornish, Manx, and Breton, so the word remains alive in discussions of heritage and identity across the British Isles and western France. Separately, in archaeology, a celt denotes a prehistoric stone or bronze tool with a beveled cutting edge. Notably, the two senses differ in pronunciation: the people take a hard /k/, while the tool takes an /s/ sound.
A member of a group of ancient peoples speaking Celtic languages, inhabiting much of Europe before and during the Roman era.
"Scholars debate how far east the influence of the Celts extended."
Pronounced with a hard /k/ sound; always capitalized in this sense.
(Archaeology) A prehistoric stone or metal implement resembling an axe or chisel, with a beveled cutting edge.
"Among the artifacts was a finely worked stone celt several thousand years old."
Pronounced /sɛlt/, rhyming with 'belt'; used mainly in technical archaeological writing.
Standard English plural; applies to both senses, though the tool sense is more often treated as a countable artifact type.
"The Celts left behind intricate metalwork and distinctive burial practices."
The stone tool called a celt rhymes with 'melt' — but the people called Celts are pronounced with a hard K, thanks to scholars reviving the Greek spelling.

Etymology of celt
The word Celt derives from Latin Celtae and Greek Keltoi, names classical authors applied to the peoples of central and western Europe. English adopted it in the late Middle Ages through Latin sources, and its hard /k/ pronunciation reflects a later scholarly revival of the Greek form. The archaeological tool sense, pronounced /sɛlt/, entered English separately in the 18th–19th century, apparently via French celte, of obscure ultimate origin but possibly influenced by the name of the people. Its cognates include Celtic and related scholarly terms.

How celt is actually used
The ethnic sense is pronounced /kɛlt/ (hard C), while the archaeological-tool sense is pronounced /sɛlt/. The ethnic sense often carries cultural pride in Ireland, Scotland, Wales, Cornwall, and Brittany; capitalized when referring to the peoples. The tool sense is technical and largely confined to archaeology.
Easily confused with celt
A kelt is an alternative spelling of 'kelts' — specifically a sea-run salmon that has spawned — whereas a Celt is a member of the Celtic peoples; the tool sense of 'celt' (/sɛlt/) is likewise unrelated to the fish.
Though 'selt' appears in 'seltzer', it comes from the German town Selters and has no connection to the word Celt.
