Korean sentences have spaces and punctuation just as English sentences do. If they did not have any punctuation or spaces, it might take several days for foreigners to understand a written page. Basically, there must be a space between two words and every sentence must be finished with punctuation. However, some lexical items, like case markers, must be attached to words.
|father||into the bag||is getting in|
|My father is getting into the bag.|
|father||into the room||is going in|
|My father is going into the room.|
