In a large mixing bowl, combine the flour, yeast, salt, and sugar. Mix well.
Slowly add the warm water and mix until the dough comes together.
Knead the dough for about 10 minutes, or until it becomes smooth and elastic.
Cover the bowl with a damp cloth and let the dough rise in a warm place for about 1 hour, or until it has doubled in size.
Preheat the oven to 220C (428F).
Shape the dough into a loaf and place it in a greased loaf pan.
Let the loaf rise for another 20-30 minutes.
Bake the bread for about 30-40 minutes, or until the crust is golden brown.
Let the bread cool before slicing and serving.
Note: You can add some caraway seeds or other ingredients like linseed, poppy seeds, sesame seeds, sunflower seeds, flaxseed, pumpkin seeds or rolled oats to the dough to give it a unique taste.
