Perhaps you should try some spelling variations:
"autodidact" » "autodidacts", "autodidactic", "autodidatta"
"autodidacta" » "autodidactsa", "autodidactica", "autodidattaa", "autodidactic"
"autodidactus" » "autodidactsus", "autodidacticus", "autodidattaus", "autodidactic"
"autodidakten" » "autoritaten", "autodidaktischen"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("autodidact" OR "autodidakt") OR (("autodidacta" OR "autodidakten") OR "autodidactus")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"autodidact\" or \"autodidakt\") or ((\"autodidacta\" OR \"autodidakten\") or \"autodidactus\"))".
• Removing quotes may allow a broader search: (( autodidact or autodidakt ) or (( autodidacta OR autodidakten ) or autodidactus )).
• Adding a wildcard symbol may retrieve word variants: (("autodidact" or "autodidakt") or (("autodidacta" OR "autodidakten") or "autodidactus"))*.
