"fink:boned vivant" » "fink:borned vivant", "fink:bonoed vivant", "fink:bonded vivant", "fin:boned vivant", "link:boned vivant", "find:boned vivant", "fink:bond vivant", "fink:bone vivant", "fink:bonet vivant"
"fink:otono vivant" » "fin:otono vivant", "link:otono vivant", "find:otono vivant"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("wikt:bon vivant") OR ((("fink:boned vivant") OR ("fink:otono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"fink:boned vivant\") OR (\"fink:otono vivant\"))))".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( fink:boned vivant ) OR ( fink:otono vivant )))).
• Adding a wildcard symbol may retrieve word variants: (("wikt:bon vivant") OR ((("fink:boned vivant") OR ("fink:otono vivant"))))*.
