Wide - A call for indicating that the ball has landed outside the court i.e. ahead of the sideline.

Wild Card - Refers to a player who gets an entry in a tournament even though his/her rank is not adequate or he/she didn't register on time. It all happens due to the discretion of the organizers. All ATP and WTA tournaments have vacant spots for wild cards entry in both the main draw and the qualifying draw. 

Winner -  An outstanding shot, which is impossible to hit by the opponent and the player gets the winning point. For e.g. when player A hits the ball and Player B is not able to reach it, then it's called a Winner for Player A.

WTA -  Acronym for Women's Tennis Association, the main authorized body of women's professional tennis that manages the WTA Tour with the biggest tournaments for women. It is established to make a better future for women's tennis.

WTA Finals -  The annual season-ending tournament that features eight of the top-tier women in the world along with two alternates.  


Zero Pointer -  Ranking points get by skipping chosen professional tennis tour events, which a top-ranked player is dedicated to partaking in (compulsory tournaments). Therefore, the player risks receiving no points added to their ranking even when partaking in an optional tournament in place of the compulsory event.
