Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidakt", "autodidactus"
"autodidactic" » "autodidactaic", "autodidaktic", "autodidactusic", "autodidaktisch", "autodidakt"
"autodidacts" » "autodidactas", "autodidakts", "autodidactuss", "autodidactus", "autodidacta", "autodidakt"
"autodidacticism" » "autodidactaicism", "autodidakticism", "autodidactusicism", "autodidaktischism", "autodidaktism"
"autodidaktens" » "autodidactes", "autodidaktin", "autodidakt", "autoritatens", "autodidaktischens"
"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 ("autodidactic" OR (("autodidacts" OR "autodidacticism") OR ("autodidaktens" OR "autodidakten")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"autodidact\" or (\"autodidactic\" or ((\"autodidacts\" or \"autodidacticism\") or (\"autodidaktens\" OR \"autodidakten\"))))".
• Removing quotes may allow a broader search: ( autodidact or ( autodidactic or (( autodidacts or autodidacticism ) or ( autodidaktens OR autodidakten )))).
• Adding a wildcard symbol may retrieve word variants: ("autodidact" or ("autodidactic" or (("autodidacts" or "autodidacticism") or ("autodidaktens" OR "autodidakten"))))*.
