Perhaps you should try some spelling variations:
"autodidact" » "autodidatta", "autodidakten"
"autodidactus" » "autodidattaus", "autodidaktenus", "autodidakten"
"autodidacta" » "autodidattaa", "autodidaktena", "autodidakten"
"autodidacts" » "autodidattas", "autodidaktens", "autodidakten"
"autodidactics" » "autodidattaics", "autodidaktenics", "autodidacticism", "autodidactas", "autodidactes", "autodidaktischs", "autodidaktens"
"autodidactic" » "autodidattaic", "autodidaktenic", "autodidaktisch", "autodidakten"
"autodidakt" » "autodidakten"

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 ("autodidactus" OR "autodidacta")) OR "autodidakt") OR ("autodidacts" OR ("autodidactics" OR "autodidactic"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((\"autodidact\" or (\"autodidactus\" OR \"autodidacta\")) or \"autodidakt\") or (\"autodidacts\" or (\"autodidactics\" or \"autodidactic\")))".
• Removing quotes may allow a broader search: ((( autodidact or ( autodidactus OR autodidacta )) or autodidakt ) or ( autodidacts or ( autodidactics or autodidactic ))).
• Adding a wildcard symbol may retrieve word variants: ((("autodidact" or ("autodidactus" OR "autodidacta")) or "autodidakt") or ("autodidacts" or ("autodidactics" or "autodidactic")))*.
