Activate the Yeast: In a small bowl, combine the warm water and sugar. Sprinkle the yeast on top and let it sit for about 5 minutes, until it becomes frothy.

Mix the Dough: In a large mixing bowl or stand mixer, combine the flour and salt. Add the yeast mixture and softened butter. Mix until a dough forms.

Knead the Dough: Knead the dough by hand on a floured surface or with the stand mixer for about 10 minutes, until it becomes smooth and elastic.

First Rise: Place the dough in a lightly greased bowl, cover with a damp cloth, and let it rise in a warm place for about 1-2 hours, or until it has doubled in size.

Shape the Dough: Punch down the dough to release the air. Shape it into a loaf and place it in a greased bread loaf pan.

Second Rise: Cover the loaf with a damp cloth and let it rise again for about 1 hour, or until it has doubled in size.

Bake the Bread: Preheat your oven to 375°F (190°C). Bake the bread for 30-35 minutes, or until it is golden brown and sounds hollow when tapped.

Cool the Bread: Remove the bread from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely before slicing.
