Perhaps you should try some spelling variations:
"dependen theory" » "dependent theory", "depende theory", "desprenden theory"
"dependet theory" » "dependent theory", "depende theory", "dependente theory"
"depended theory" » "depende theory", "defended theory", "dependent theory"
"depender theory" » "depende theory", "defender theory", "dependent theory"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dependen theory\") OR (\"dependet theory\"))) OR (((\"depended theory\") OR (\"depender theory\"))))~".
• Removing quotes may allow a broader search: (((( dependen theory ) OR ( dependet theory ))) OR ((( depended theory ) OR ( depender theory ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("dependen theory") OR ("dependet theory"))) OR ((("depended theory") OR ("depender theory"))))*.
