OmegaT glossary

New in version 1.5.1.

OmegaT allows a translator to create a terminology list of glossary files. It uses this file to provide its glossary matches to the OmegaT users.

Format specifications

The glossary files is a tab delimited files with three columns:

  1. source
  2. target
  3. comment

The files is stored in the system locale if the files extension is .txt or in UTF-8 if the file extension is .utf8.


The implementation can load files in UTF-8 or the system encoding.


  • There has not been extensive testing on system encoded files and there are likely to be issues in these files for encodings that fall outside of common ASCII characters.
  • Files with additional columns are read correctly but cannot be written.
