Hundred years ago, in 1918, when the First World War ended. A few months later that, in a diary entry dated September 10, 1918, the term entered the English language. We didn't wait for the Second World War to coin the word "First" before the only World War the world had seen at the time.

Though it was called the Great War or the War To End Wars prior to this, the changing terminology in a way, the decision predicted the future yet to unfold.

The year 1918 saw a great many improvements on the planet apart from the World War and the incredible number of "new things" happening created the need for a lot of new words.

Around 524 new words joined the English language that year --- 333 by the Oxford English Dictionary and 191 by America's Merriam-Webster.

Below are 15 English words which entered the language in 1918 and have stayed with us changed or unchanged 100 years down the line:
