"wikt:bon vivant" » "witt:bon vivant", "wit:bon vivant", "wilt:bon vivant", "wikt:born vivant", "wikt:bono vivant", "wikt:bond vivant", "wickt:bon vivant", "winkt:bon vivant"
"wikt:tono vivant" » "witt:tono vivant", "wit:tono vivant", "wilt:tono vivant", "wikt:torno vivant", "wikt:otono vivant", "wikt:todo vivant", "wickt:tono vivant", "winkt:tono vivant"
"wik:cono vivant" » "wick:cono vivant", "wink:cono vivant", "wik:con vivant", "wik:como vivant", "wik:mono 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 ((("wikt:tono vivant") OR ("wik:cono vivant"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:bon vivant\") OR (((\"wikt:tono vivant\") OR (\"wik:cono vivant\"))))".
• Removing quotes may allow a broader search: (( wikt:bon vivant ) OR ((( wikt:tono vivant ) OR ( wik:cono vivant )))).
• Adding a wildcard symbol may retrieve word variants: (("wikt:bon vivant") OR ((("wikt:tono vivant") OR ("wik:cono vivant"))))*.
