The table below lists all lexical data sources (dictionaries, thesauri, wiktionaries, WordNets, and similar) currently registered in PanLex. All registered sources have been acquired (files downloaded or book purchased and scanned), but not all have been ingested (data analyzed and incorporated into the PanLex database).The denotations column indicates how many words are in the source. For ingested sources, this is an exact number. For not yet ingested source, it is an estimated number (indicated with “(est.)”), or “unknown” if an estimate is not available.
