Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidactus", "autodidatta"
"autodidacts" » "autodidactas", "autodidactuss", "autodidattas", "autodidactus", "autodidacta", "autodidakten"
"autodidactics" » "autodidactaics", "autodidactusics", "autodidattaics", "autodidacticism", "autodidactus", "autodidactas", "autodidaktischs", "autodidaktens"
"autodidactes" » "autodidactaes", "autodidactuses", "autodidattaes", "autodidactus", "autodidactas", "autodidactos"
"autodidactic" » "autodidactaic", "autodidactusic", "autodidattaic", "autodidaktisch", "autodidakten"
"autodidakt" » "autodidakten"
"autodidattaes" » "autodidatta", "autodidactas", "autodidatas"

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