There are several theories about how “love” came to mean “zero” in tennis. One, that dates back to the 1700s, is that when you have no score, but you still give it all you’ve got, then you are playing for the love of the game. This is a slightly more credible theory, because, according to the Webster’s 1828 Dictionary, the word “amateur” comes from the Latin words anator (“a lover”) and amo (“to love”), referring to a person who does something for love rather than for money.

Of course, every professional begins as an amateur and one could argue that every professional wants to feel the way they did when they were an amateur — as if nothing else matters, but that moment and the love of the game in that moment. And, this is where things get interesting; because, in tennis, the most prestigious tournaments are “open” to amateurs and professionals. They all play for the same stakes. They all play with love so palpable it can make other people fall in love with the game. Some even play with the kind of passion that can also change the face of the game.
