| A spoken language is like a person: it grows and changes. One way its changes is by adding new words and phrases, usually through borrowing. Just as someone borrows a pencil from a classmate in order to finish work, languages borrow words from other languages in order to fill what is called a "word gap". A word gap happens when a language has no term, synonym, or easy translation for an object or activity. One way a language finds something to fill a word gap is to borrow a word from another language. Unlike a person, language never really returns words to their starting place. Instead, the words remain and become part of the borrowing language. We see this borrowing course at work in English in different ways and for different reasons. English, like any other language, will probably continue to borrow words from other languages as long as it continues to change — in other words, for as long as people continue to speak.
