In a large mixing bowl, combine the warm water, sugar, and yeast. Let it sit for 5-10 minutes until it becomes foamy. This shows the yeast is alive and ready to work.
Mix the dough
Add the milk, melted butter, and salt to the yeast mixture. Stir gently. Then gradually add the flour, one cup at a time, until a soft dough forms.
Knead the dough
Turn the dough out onto a lightly floured surface. Knead for about 8-10 minutes until the dough is smooth and elastic. If using a stand mixer, knead with the dough hook for 5-6 minutes.
Let it rise
Place the dough in a greased bowl, cover with a towel, and let it rise in a warm spot for 60 minutes or until doubled in size.
Shape the loaf
Punch down the dough, then shape it into a loaf. Place it in a greased loaf pan and let it rise again for about 30 minutes.
Bake
Preheat the oven to 375°F (190°C). Bake the loaf for 30 minutes or until golden brown and hollow-sounding when tapped.
Cool and enjoy
Brush the top with a bit of melted butter for that glossy finish. Let the bread cool on a wire rack before slicing.
