Etymology
Origin of Java
1550–60; of obscure origin; possibly from Sanskrit yāvadvīpa, yāvaka dvīpa “barley island” (the island was well known for the barley plant)
Explanation
Java is an informal word for "coffee," so the next time you go out for breakfast, you can jauntily order a cup of java. In North America, java has been slang for "coffee" since about 1850. Java is a coffee-producing region of what was then the Dutch East Indies and is now Indonesia, and while the term originally referred to coffee grown in Java, by the 20th century it was shorthand for any coffee. If you use this word these days, you're just as likely to be talking about the computer programming language called Java.
