Why do so many tennis stars have "Wa" after their names?

"This is a Slavic suffix, and the Roman letter ends with -va, which is specially used to address women" is not entirely correct.

In fact, male surnames in Russia and Eastern European countries often end with "-v", such as Gorbachev. And a man's wife and daughter take the man's surname, and her surname is the negative number of the man's surname = that is, add "a" at the end. This is only a change in part of speech, not "specifically used to address women." Such as Maria Sharapova +a, her father (Yuri Sharapova) and Sharapova.

Va and Wa are similar in pronunciation, so they are translated into "wa". In fact, there are not many "Wa" in the United States. Shawa immigrated to the United States but still retains Russian citizenship, so the "tile" of the United States still comes from Russia and Eastern Europe. Since she is a Slavic, she must obey Slavic, which is not a matter of custom.
