PORTHOLES Meaning and
Definition
-
Portholes are small, circular windows typically found on the sides of ships, submarines, or aircraft fuselages. They are designed to allow natural light and fresh air into the interior spaces, as well as provide a means for observing the outside world.
In terms of ships, portholes are essential components of naval architecture. They are usually located along the hull, providing a source of ventilation and illumination for crew and passengers. Portholes are often equipped with a hinged cover called a scuttle, allowing for easy opening or closing depending on weather conditions. Additionally, portholes seal tightly to keep water out, ensuring the vessel remains watertight during rough seas.
On submarines, portholes serve similar purposes, but their primary role is to allow the crew to visually inspect the surroundings, particularly when the submarine is submerged. These portholes, also known as viewports, are made with special materials such as thick glass or acrylic that can withstand the tremendous pressure of the deep ocean.
In the context of aviation, portholes refer to the small windows found on aircraft fuselages. Although less common than traditional rectangular windows, portholes can be seen on some vintage or small aircraft. They serve the same purposes of providing light and vision to the cabin, but are usually sealed shut during flight to maintain structural integrity and prevent any disturbances in air pressure.
Overall, portholes function as vital components of various modes of transportation, allowing for both practical functionality and aesthetic appeal.
Common Misspellings for PORTHOLES
Etymology of PORTHOLES
The word "portholes" originated from the 16th-century English word "port", which referred to an opening in a ship's side for firearms to be fired from. The term was derived from the Latin word "porta", meaning "door" or "gate". Later, in the 19th century, these openings were made smaller and circular in shape to allow light and air into the ship's interior, and they were known as "portholes". The term combines "port" with "hole" to describe these round openings in the sides of ships. Over time, "portholes" also came to be used to refer to similar circular openings in other structures, such as submarines or aircraft.
