After the long walk, we frowst in the greenhouse, enjoying the humid, cozy heat.

After hours of sealing the windows, a heavy frowst settled over the small study, making concentration impossible.

We spent the afternoon frowsting in the tiny conservatory, the air thick and motionless.

During the heatwave, the old house's frowsts made it unbearable to stay inside.

Every afternoon he frowsts by the window, brooding over the letters he never sent.

We frowsted in the stuffy parlor all afternoon, unwilling to open the windows.

After a week without ventilation, the basement felt frowstier than before.

The frowstiness of the closed attic made everyone step outside for a breath of fresh air.

Of all the rooms in the old manor, the attic was the frowstiest, thick with dust and the scent of mildewed books.

The frowsty attic was filled with boxes of forgotten toys and a faint scent of mildew.
