Frost surname meaning

Frost is an English, German, Danish, and Swedish nickname from the common Germanic word for frost or ice (Old English forst/frost, Old Norse frost, Old High German frost). It could mark someone who suffered from cold, seemed “frosty” or unfriendly, or looked as if covered with frost—white hair or a white beard. Some older writers also treat Frost as a seasonal baptismal byname for a child born in hard frost, like Christmas or Nowell. Froste is a historical spelling. Nickname is the catalog type, and the frost-word etymology is high confidence.
