Cross, ace, split-step, Continental grip: the Tennis ABC explains every term from our guides in plain language – your starting point before technique guides.
## Introduction Reading your first tennis guide and tripping over words like "Cross," "Split-Step," or "Continental Grip"? No worries – every sport has its own language, and tennis has an especially dense one, because grips, shot types, and tactics all get named with real precision. This Tennis ABC walks you through every important term in plain, friendly language, so you can follow our technique guides right away – no constant looking-up required.
## Gear & Grips Racket: Sounds basic, but it's a real precision tool – the grip size (L1 to L5) decides how it sits in your hand. Too thick and you tense up, too thin and it slips.
Overgrip: A thin wrap that goes over the actual handle. Soaks up sweat, stops slipping, and is easy to swap once the racket gets slick after a few sessions.
Strings (Besaitung): The tensioned strings across the racket head that actually touch the ball. Strung tighter means more control, strung looser means more power and more comfort for your wrist.
Continental Grip (Hammer Grip / Continental-Griff): The base grip for serve, volley, and slice. You hold the racket as if you were hammering a nail into a wall with the edge – hence the nickname.
Eastern & Semi-Western Grip: Two classic forehand grips with the hand rotated further around the handle. Eastern is the traditional compromise of power and control, Semi-Western the modern pro standard for heavy topspin – you brush up through the ball almost like a windshield wiper.
## The Court Baseline (Grundlinie): The back line most rallies are played from – your home base during the point.
Service Line (T-Linie): The line that splits the front service area into two halves, drawing a big "T" on the court.
Net: Lower in the middle than at the edges – about 15 centimeters, roughly a hand's width. That's exactly why the diagonal shot is safer than the straight one.
Cross & Down-the-Line (Longline): Cross means hitting diagonally across the court, down-the-line means hitting straight along the sideline. Cross is the safer default, because the net sits lower there and the court gives you more room to land the ball.
## Technique & Shots Forehand: The shot on the side of your racket hand – for most players the most natural and powerful groundstroke.
Backhand: The shot on the other side of your body, hit either one- or two-handed. Two-handed is usually more stable and easier for beginners to control.
Serve & Toss: The opening shot of every point. The toss is the throw where you feed yourself the ball before you hit it.
Volley: A shot struck straight out of the air, usually at the net – you're more or less "blocking" the ball rather than swinging fully through it.
Lob: A high, deep ball hit over your opponent's head. Your emergency card whenever you're under pressure and need a couple of seconds to reset.
Slice: A shot with backspin – the ball flies flat over the net and skids low after the bounce. Handy for taking pace off and breaking your opponent's rhythm.
Topspin: Forward spin you create by brushing up the back of the ball. Sends it over the net on a safe, arcing path, then dips steeply down into the court.
Split-Step: A small, two-footed hop timed exactly to the moment your opponent makes contact. Puts you in a loaded, ready position to explode in any direction.
Contact Point (Treffpunkt): The exact spot where racket meets ball – usually well in front of your body, for maximum control and power transfer.
Kinetic Chain: The principle that power doesn't come from the arm, but travels from the legs through the hips and into the racket head – like the crack of a whip.
## Tactics & Scoring Rally (Ballwechsel): The sequence of shots between the serve and the end of the point.
Unforced Error & Winner: An unforced error is an avoidable mistake made without pressure from your opponent; a winner is a shot your opponent can't even reach. Even pros win most points on their opponent's errors, not on spectacular winners.
Ace: A serve your opponent doesn't even touch – the point goes straight to the server.
Double Fault: Two missed serves in a row. The point goes automatically to your opponent, without them having to hit a single shot.
Break Point & Break: The chance to win a game on your opponent's own serve – one of the most valuable and hard-fought moments in any match.
Set, Match Point & Tiebreak: A match is made up of several sets. Match point is the point that ends the entire match. If a set reaches 6-6, it's usually decided by a tiebreak – a short, high-tension extra game.
Percentage Tennis: The strategy of always choosing the statistically safest shot instead of the flashiest one. Even the world's best players win only about 55% of all points on average.
Depth (Länge): A ball has "good depth" when it lands close to your opponent's baseline, making it hard to attack.
## Pro Tip You don't need to memorize every term at once. Read this Tennis ABC through once, then grab your first technique guide – and come back here whenever a word trips you up again. Terms stick far better once you see them in action instead of just cramming them.
### What does "cross" mean in tennis? Cross means hitting the ball diagonally across the court instead of straight down the sideline (down-the-line). It's the safer default shot, because the net sits lower in the middle and the diagonal gives you more room to land the ball – ideal for beginners who want to build safety before risk.
### What is an ace in tennis? An ace is a serve your opponent doesn't even touch – usually because it's perfectly placed, extremely fast, or catches them off guard. The point goes straight to the server. Aces are rare for beginners, but a smart, well-placed serve counts every bit as much.
### What is the Continental grip? The Continental grip, also called the hammer grip, is the base grip for serve, volley, and slice. You hold the racket as if you were hammering a nail with the edge. It feels unfamiliar at first, but it's essential because it works across several shots without regripping.
### What is an unforced error? An unforced error is an avoidable mistake you make without your opponent putting you under any pressure – for example, an easy ball that ends up in the net. Even among pros, most points come from errors like this, not spectacular winners. Safety beats risk almost every time.
### What's the difference between a forehand and a backhand? The forehand is hit on the side of your racket hand – usually the most natural and powerful groundstroke. The backhand is hit on the other side of your body, either one- or two-handed. Most beginners find the backhand a bit less intuitive at first, but it becomes just as reliable with practice.
