Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidacts", "autodidakt"
"autodidactic" » "autodidactaic", "autodidactsic", "autodidaktic", "autodidaktisch", "autodidakten", "autodidakt"
"autodidactics" » "autodidactaics", "autodidactsics", "autodidaktics", "autodidaktischs", "autodidaktens", "autodidakts", "autodidacticism", "autodidactus", "autodidacts"
"autodidactaics" » "autodidactaaics", "autodidactsaics", "autodidaktaics", "autodidactas", "autodidacticism", "autodidacta"

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 ("autodidactics" OR "autodidactaics"))).
• Removing quotes may allow a broader search: ( autodidact or ( autodidactic or ( autodidactics or autodidactaics ))).
• Adding a wildcard symbol may retrieve word variants: ("autodidact" or ("autodidactic" or ("autodidactics" or "autodidactaics")))*.
