Like a human being, each word has a story. To understand a word, we need to learn where it was born, what paths it took to reach where it is today and how it has changed along the way.
[T]hat's how a language grows. Old words die - or take on a new life. New words appear. Language wordstock is replenished, refreshed, and the language remains vibrant and serviceable, ready to describe new concepts, ideas, and objects. Many language purists object to this way of growth. But we have to remember that just as yesterday's liberal is often tomorrow's conservative, in many cases, what was considered slang in the past, eventually acquires respectability.
As quoted in Dickson, Paul (2014), Authorisms: Words Wrought by Writers
For as long as I can recall, I enjoyed reading. I literally read books from cover to cover. Then I started wondering where words come from. Who made them up? Who said that that opening in a wall was to be called a window? Then I discovered that each word comes with a biography. These words have fascinating stories to tell, if only we take the time to listen. For example, the word window comes from Old Norse in which it meant wind's eye. How much more poetic can you get?
