Offline Dictionary
Offline Dictionary lets you search a dictionary file from the same place as your other Definer sources. It is useful when you have a specialized dictionary, a language resource, or a reference archive that you want to use in lookups.
A dictionary package is the file or group of files you downloaded. Importing installs that package on this device. An Offline Dictionary source chooses one installed package and displays its matching entries in Definer.
Install and try a dictionary
- Open Definer Options → Sources → Content sources, select New source, then open Constructor.
- Under Drop a file here, drop a supported package or select Choose files. For a dictionary stored as several files, select Choose dictionary folder instead.
- Keep Definer Options open until the import finishes. The dialog closes and an enabled Offline Dictionary source appears in the Content list.
- Open the new source's Settings. In Preview: Offline Dictionary, enter a familiar headword in Test query and press Enter. A matching entry should appear in the preview.



If Definer cannot recognize the package, check the supported dictionary formats and required files before trying again.
