Pronunciation: [stˈɑː ʃˈɛl] (IPA) 
The correct spelling of the word "star shell" is /stɑːr ʃɛl/. The first part of the word is spelled with an "a" followed by two "r's" to indicate the long "a" sound, while the second part is spelled with "sh" and "e" followed by an "l" to indicate the "shel" sound. A star shell is a type of military ammunition used to illuminate enemy positions at night, typically fired from a mortar or artillery gun.
A star shell refers to an explosive projectile typically fired from a firearm or artillery piece, designed to create a bright light or illuminate a specific area. It is commonly used in military operations for signaling, illuminating the battlefield, or providing visibility during nighttime combat.
The shell itself consists of a hollow casing containing various chemical compounds and a bursting charge. Once fired, the bursting charge detonates within the shell, causing it to burst or fracture and disperse its contents. The primary purpose of a star shell is to release a brightly burning pyrotechnic concoction upon explosion, producing a luminous flare in the sky. The burning compounds within the shell generate a distinct star-like appearance, hence the name "star shell."
Star shells have been employed in warfare since the late 19th century, evolving from simple hand-fired projectiles to advanced artillery-based systems. These shells are typically fired high into the air, reaching sufficient altitude to allow the ignited pyrotechnic mixture to burn for an extended period while descending slowly and safely, providing ample illumination for an extended duration.
The use of star shells helps military forces to overcome the challenges posed by low-light conditions, allowing them to spot and identify targets, monitor movements, or guide operations during the night. Additionally, they serve as effective visual markers and communicative tools for coordinating troops or requesting support.
In summary, a star shell is an explosive ammunition designed to create a bright, star-shaped illumination in the sky, aiding visibility and assisting military operations in low-light conditions.
The word "star shell" is derived from the combination of two words: "star" and "shell". Here is the etymology of each word:
1. Star: The word "star" comes from the Old English word "steorra", which is akin to the Old High German word "stern" and Old Norse word "stjarna". These words trace back to the Proto-Germanic word "*sternō", meaning "star". The origin of Proto-Germanic word is uncertain, but it possibly has Indo-European roots.
2. Shell: The word "shell" originated from the Old English word "scealu" or "sceol" which referred to a covering or husk. It is related to the Old High German word "scala" and Old Norse word "skel", both meaning "shell" or "husk".
