One of the ten wooden objects, shaped rather like bottles with narrow necks, that stand in a triangle at the end of a bowling lane waiting for you to knock them down with a heavy ball. That is the strict meaning: one pin. But in real use you meet the word mostly in two other shapes. As a plural, tenpins, meaning the game itself — mainly American. And as the first half of tenpin bowling, the full name of the sport, which is what British speakers usually say to separate it from other bowling games their country has, like tenpin's cousin with smaller pins. Americans just say bowling and everyone knows. Day to day, if you are standing in the alley, you and your friends will simply call them pins — "I only knocked down three pins." The full word tenpin turns up more in the name of the sport, on signs, and in writing about it. Knocking all ten down with one ball is a strike; doing it in two is a spare.
