In a large bowl, combine the flour, yeast, salt, and sugar. Stir them together until well mixed.

Gradually pour in the warm water, stirring with a wooden spoon until a shaggy dough forms. It should be sticky but manageable.

Flour a clean surface and turn the dough out. Knead it for about 8-10 minutes until smooth and elastic.

Place the dough in a lightly greased bowl, cover with a kitchen towel, and let it rise in a warm spot for about 1-2 hours or until doubled in size.

Punch down the dough and turn it out onto a floured surface. Shape it into a loaf and place in a greased loaf pan. Cover and let rise for another 30-45 minutes.

Preheat your oven to 375°F. Bake the loaf for 30-35 minutes until golden brown and sounds hollow when tapped.

Let it cool in the pan for a few minutes, then turn it out onto a wire rack and allow to cool before slicing.
