OED Text Annotator beta

The OED Text Annotator beta has been designed to annotate texts written between 1750 and the present day using lexical information derived from the OED.


To use the OED Text Annotator beta, you simply upload your text as a plain-text file and the approximate date when the text was written; this can help to improve the accuracy of annotation.

Your text will be annotated with:

  • Etymology type
  • Languages of immediate etymon
  • Languages of ulterior etymon
  • Contemporary frequency
  • Modern frequency
  • Dates in use
