Ubiquitous in many classrooms since the 19th century, chalk and chalkboards are familiar to most of us. White, powdery and prone to sticking to those surfaces where it is put (and just as easy to wipe away), chalk and its accompanying board are excellent instructional aids. Notably, however, most chalk today isn’t technically chalk at all, but gypsum.

@LagiNaLangAko23 That one goes right back to luggage. The old cars would just have a rack and people would strap down a luggage trunk to the back to store things.

Regarding the trunk of a car, you did not mention that for a couple of decades in the early 1900s a trunk was often strapped at the back of a car. Ford Model A's can be seen with this feature. As automakers learned how to better manipulate sheet metal this feature was integrated into the design of a car rather than having a separate trunk riding at the back of the car.

If you cram your swimsuits into your footwear, which you place into a storage container, then that into the rear compartment of a 4-door car, while driving on a major road, and switch freely between American and British English, you can have trunks in boots in a trunk in the boot on the trunk.

@tomt6963 4 года назад

In the typical German way, the trunk of a car is called "Kofferraum" , which translates into "suitcase space." The trunk of an elephant is called "Rüssel", a word used for All protuding, flexible animal snouts, Loke armadillos, tapirs, pigs and the sucking apparatus of insects like fleas or moskitos.

And then there is "trunk" as used in telecommunications, referring to a phone circuit connected to a multi-user business phone system. This comes from railroard days when phone lines were run along railroad tracks. A railroad going between hubs was a "trunk line", and so were the phone lines that ran on such a route. And railroad "trunks" were called this because they were used to transport passenger luggage, which mostly consisted of ... trunks.

@christophersmith8014 4 года назад

We also use the similar word "truck" to mean the act of carrying something around or to convey it from one place to another. Which also fits most of the uses for the word trunk. Generally they both deal with holding something for the sake of carrying it to another place. A pipe carries air, water, and sound just like the elephants trunk. A cargo chest contains and protects items for shipping. Swimming trunks are probably more to do with the truncation of pants as many people have commented, but they also protect your genital cargo as you carry yourself about. So you could also see how it could mean to protect and shield from harm. A truck is a stronger means of conveyance than a car. Elephants use their trunks to smack predators around. etc.

Wikipedia. The usage of the word "trunk" comes from it being the word for a large travelling chest, as such trunks were often attached to the back of the vehicle before the development of integrated storage compartments in the 1930s; while the usage of the word "boot" comes from the word for a built-in compartment on a horse-drawn coach (originally used as a seat for the coachman and later for storage). The usage of the word "dickie" comes from the British word for a rumble seat, as such seats were often used for luggage before cars had integrated storage.

Trunk is also used in telecom. A trunk line is a physical connection, either copper or fiber optic, used to connect two remote systems together. A T1 is one of the more common types of trunk in telecom, along with others. There are also trunks in both data(ethernet trunking) and radio. I assume the idea for these all came from the idea of a tree trunk, a tree's connection between ground and sky.

@allanrichardson1468 4 года назад

Gypsum has two other uses: art and medicine. Both of them use the same chemical reactions as are used in construction. Each set of calcium and sulfate (SO4) ions is accompanied by seven (7!) water molecules filling some of the space between ions, making the crystal structure tough and solid. Thus, the chemical name of natural gypsum is calcium sulfate heptahydrate. Heating a piece of gypsum drives out the water molecules, making it crumble into a powder, calcium sulfate hemihydrate (meaning one molecule of water for each TWO sets of ions), commonly called Plaster of Paris, or just plaster. The powder can be mixed with water to form a slurry or paste, which can be poured into molds to make copies of statues or other solid objects, as the powdered crystals absorb the water to recreate the hard, solid gypsum. The process also produces heat, as the ions and water molecules shift into a lower energy structure. Plaster of Paris is also used to make casts to set broken bones. Rolls of gauze fabric with embedded grains of plaster are dipped in water and wrapped around the limb, where they harden. The name Plaster of Paris comes from the large quarrying and preparation industry near Paris in the 18th century.
