"Pen" and "valley" are both nouns that refer to different objects.

1. Pen:
- A pen can refer to a writing instrument that uses ink to create markings on paper or other surfaces. It typically consists of a hollow, cylindrical tube with a pointed tip, inside which ink is stored. To write with a pen, you hold it upright and apply gentle pressure as you move it across the surface.
- Pen can also refer to an enclosure or an area where animals, particularly livestock or poultry, are kept. It is usually surrounded by fences or walls and provides a confined space for animals to be contained.

2. Valley:
- A valley is a low-lying area of land between two higher points, such as hills or mountains. It is usually formed by the erosion of water or ice, and often contains a river or stream running through it. Valleys are characterized by their sloping sides and flat or gently curving bottom, and they are often known for their natural beauty.
- Figuratively, the term "valley" can also be used to describe a low point or a period of difficulties or challenges that a person or group may go through.
