"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wilt:bon vivant", "wikt:bono vivant", "wikt:bond vivant", "wikt:bone vivant", "winkt:bon vivant"
"wik:bon vivant" » "wik:bono vivant", "wik:bond vivant", "wik:bone vivant", "wink:bon vivant"
"wik:born vivant" » "wink:born vivant", "wik:korn vivant"
"wick:born vivant" » "wick:korn vivant", "nick:born vivant", "dick:born vivant", "rick:born 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 ((("wik:bon vivant") OR ((("wik:born vivant") OR ("wick:born vivant"))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wik:bon vivant\") OR (((\"wik:born vivant\") OR (\"wick:born vivant\"))))))*".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wik:bon vivant ) OR ((( wik:born vivant ) OR ( wick:born vivant ))))))*.
