Notice how two sentences begin with the word For? It’s kind of old-timey, antique language, but you can begin a sentence with For to explain something you’ve just said. For example:
- He would wear a coat outside in the wind. For he couldn’t bear to be inside.
- He loved being in storms. For he was a storm boy.
You could join these sentences together with a comma and they still mean the same thing:
- He would wear a coat outside in the wind, for he couldn’t bear to be inside.
- He loved being in storms, for he was a storm boy.
But the change in rhythm changes the feeling a little. Using the full stop and beginning a new sentence with For slows the pace, puts in a beat that helps create that timeless, poetic feeling that runs throughout the story.
