Listen to people speak and think about trying to spell words exactly the way they say them. If you were reading a conversation and the character said, “Mon scoh,” would you know what the character meant? Does it look like a foreign language? Now try saying the made-up words out loud. You might be able to figure out what they mean. The two words are actually five different words squashed together: “Come on. Let us go.”

Writing words the way people really say them would be confusing! So writers have to decide whether to write the words exactly the way they sound coming out of the speaker’s mouth or to write them using the dictionary spellings.
