Etymology and terminology

The origin of the English word ''gun'' is considered to derive from the name given to a particular historical weapon. ''Domina Gunilda'' was the name given to a remarkably large

woman's proper name ''Gunnhildr'' which combines two Norse words referring to battle. "Gunnildr", which means "War-sword", was often shortened to "Gunna". The earliest recorded use of the term "gonne" was in a Latin document circa 1339. Other names for guns during this era were "schioppi" (Italian translation-"thunderers"), and "donrebusse" (Dutch translation-"thunder gun") which was incorporated into the English language as "blunderbuss". Artillerymen were often referred to as "gonners" and "artillers" "Hand gun" was first used in 1373 in reference to the handle of guns.

dictionary, a gun could mean "a piece of ordnance usually with high muzzle velocity and comparatively flat trajectory," " a portable firearm," or "a device that throws a projectile." Gunpowder and firearm historian Kenneth Chase defines "firearms" and "guns" in his ''Firearms: A Global History to 1700'' as "gunpowder weapons that use the explosive force of the gunpowder to propel a projectile from a tube: cannons, muskets, and pistols are typical examples."

. As such, the fire lance, which appeared between the 10th and 12th centuries AD, as well as other early metal barrel gunpowder weapons have been described as "proto-guns" Joseph Needham defined a type of firearm known as the "eruptor," which he described as a cross between a fire lance and a gun, as a "proto-gun" for the same reason. He defined a fully developed firearm, a "true gun," as possessing three basic features: a metal barrel, gunpowder with high nitrate content, and a projectile that occluded the barrel. The "true gun" appears to have emerged in late 1200s China, around 300 years after the appearance of the fire lance. Although the term "gun" postdates the invention of firearms, historians have applied it to the earliest firearms such as the

Classic gun

Historians consider firearms to have reached the form of a "classic gun" in the 1480s, which persisted until the mid-18th century. This "classic" form displayed longer, lighter, more efficient, and more accurate design compared to its predecessors only 30 years prior. However this "classic" design changed very little for almost 300 years and cannons of the 1480s show little difference and surprising similarity with cannons later in the 1750s. This 300-year period during which the classic gun dominated gives it its moniker. The "classic gun" has also been described as the "modern ordnance synthesis."

. It consisted of a bamboo tube of gunpowder tied to a spear or other polearm. By the late 1100s, ingredients such as pieces of shrapnel like porcelain shards or small iron pellets were added to the tube so that they would be blown out with the gunpowder. It was relatively short ranged and had a range of roughly 3 meters by the early 13th century. This fire lance is considered by some historians to be a "proto-gun" because its projectiles did not occlude the barrel. There was also another "proto-gun" called the eruptor, according to Joseph Needham, which did not have a lance but still did not shoot projectiles which occluded the barrel.

of which fire-lance barrels were originally made came to be replaced by metal. And to take full advantage of that power, the shrapnel came to be replaced by projectiles whose size and shape filled the barrel more closely. Fire lance barrels made of metal appeared by 1276. Earlier in 1259 a pellet wad that filled the barrel was recorded to have been used as a fire lance projectile, making it the first recorded bullet in history. With this, the three basic features of a gun were put in place: a barrel made of metal, high-

These arrows can be solid-tipped without explosives, or with explosives and incendiary materials placed behind the tip. Near the rear, there is a combustion chamber or room, which refers to the bulging part near the rear of the gun, where the gunpowder is placed. The cetbang is mounted on a fixed mount, or as a hand cannon mounted on the end of a pole. There is a tube-like section on the back of the cannon.

s" that were fired from resting Y-shaped supports appeared. The musket was able to penetrate heavy armor, and as a result armor declined, which also made the heavy musket obsolete. Although there is relatively little to no difference in design between arquebus and musket except in size and strength, it was the term ''musket'' which remained in use up into the 1800s. It may not be completely inaccurate to suggest that the musket was in its fabrication simply a larger arquebus. At least on one occasion the musket and arquebus have been used interchangeably to refer to the same weapon, and even referred to as an "arquebus musket." A Habsburg commander in the mid-1560s once referred to muskets as "double arquebuses." A

was added to the arquebus around 1470 and the matchlock mechanism sometime before 1475. The matchlock arquebus was the first firearm equipped with a trigger mechanism and the first portable shoulder-arms firearm. Before the matchlock, handheld firearms were fired from the chest, tucked under one arm, while the other arm maneuvered a hot pricker to the touch hole to ignite the gunpowder.

of Hungary (r. 1458–1490). Arquebuses were used by 1472 by the Spanish and Portuguese at Zamora. Likewise, the Castilians used arquebuses as well in 1476. Later, a larger arquebus known as a musket was used for breaching heavy armor, but this declined along with heavy armor. Matchlock firearms continued to be called musket. They were used throughout Asia by the mid-1500s.


Transition to classic guns

Guns reached their "classic" form in the 1480s. The "classic gun" is so called because of the long duration of its design, which was longer, lighter, more efficient, and more accurate compared to its predecessors 30 years prior. The design persisted for nearly 300 years and cannons of the 1480s show little variation from as well as surprising similarity with cannons three centuries later in the 1750s. This 300-year period during which the classic gun dominated gives it its moniker. The classic gun differed from older generations of firearms through an assortment of improvements. Their longer length-to-bore ratio imparted more energy into the shot, enabling the projectile to shoot further. They were also lighter since the barrel walls were thinner, allowing faster dissipation of heat. They no longer needed the help of a wooden plug to load since they offered a tighter fit between projectile and barrel, further increasing the accuracy of firearms – and were deadlier due to developments such as gunpowder corning and iron shot.

Projectile

A gun projectile may be a simple, single-piece item like a bullet, a casing containing a payload like a shotshell or explosive shell, or complex projectile like a sub-caliber projectile and sabot. The propellant may be air, an explosive solid, or an explosive liquid. Some variations like the
