Teenis

Teenis is a term that may arise as a misspelling or transliteration of tennis, the racquet sport played between two players (singles) or two teams of two (doubles). It is not recognized as a separate sport by major sporting authorities.

In practice, most references to "teenis" point to tennis rather than to a distinct discipline. The spelling is uncommon in English and is more likely the result of typographical error, phonetic variation, or regional transliteration in some texts. Because there is no separate sport named "teenis" with its own governing body, there is no independent official ruleset apart from those used in tennis.

If the term appears in branding or local contexts, it may refer to a tennis program, club, or event rather than to a global sport category. In such cases, the content typically follows standard tennis rules and practices, aligned with established guidelines.
