Pronunciation: [pˈɔːt hˈə͡ʊl] (IPA) 
"Port hole" is spelled with an "o" in "port" and a "hole" at the end. The IPA phonetic transcription of this word is /pɔːt həʊl/. The first syllable, "port," is pronounced with an open "o" sound, represented by the symbol "/ɔː/". The second syllable, "hole," is pronounced with a long "o" sound, represented by the symbol "/əʊ/".

A porthole, also known as a port hole, refers to a small, circular window typically found on the side of a ship or aircraft. It is specifically designed to allow light, air, and sometimes a limited view to enter enclosed spaces that lack natural illumination. Portholes are usually round in shape, although other shapes such as ovals and rectangles can also be found, depending on the vessel's design.
Traditionally, portholes are constructed from strong materials to withstand the harsh conditions encountered at sea or in the air. They consist of a thick glass or plastic pane attached to a metal or wooden frame that can be securely fastened to the ship or aircraft's wall or bulkhead. The porthole can be opened and closed, providing control over the amount of airflow and ventilation entering the space.
Apart from their practical functionality, portholes often serve an aesthetic purpose, adding a unique charm and nostalgia to ships and airplanes. They have been used for centuries across various maritime vessels, and are often associated with the romance and adventure of seafaring explorations.
In modern times, portholes are widely utilized in luxury cruise ships, naval vessels, and submarines. They not only function as openings for light and air but also serve as emergency exits and observation points. Additionally, portholes are occasionally featured in buildings, especially in nautical-themed architecture, contributing to the overall maritime ambiance.
The word "porthole" originated from nautical terminology. It is derived from the combination of two words, "port" and "hole".
The term "port" originally referred to the left side of a ship, based on the Latin word "portus" meaning "harbor". This term was used to distinguish the left side of a vessel from the right side, known as the "starboard" side.
The word "hole" simply refers to an opening or aperture.
The combination of these two words, "port" and "hole", came to describe the small, round openings found on the sides of ships. These portholes were installed to allow light, air, and visibility from inside the vessel, while also protecting against water and other elements.
