Etymology

fourth = four<number 4> + th<ordinal suffix>

  • four: From Old English fēower, Proto-Germanic fedwōr, ultimately from Proto-Indo-European kʷetwóres. Retains its core meaning as the number 4.
  • th: A suffix used to form ordinal numbers (e.g., fifth, sixth), derived from Old English -þa, -þe.

Etymology Origin:
The word fourth combines the ancient root for the number 4 with a Germanic ordinal suffix, reflecting a straightforward numerical ranking system. The -th suffix has been consistently used in English since Old English to denote position in a sequence, making fourth a logical and stable construction.
