cord 30秒で
- A cord is a versatile, flexible connector made of twisted strands, bridging the gap between thin string and heavy rope.
- In modern life, 'cord' most frequently refers to electrical power cables that connect appliances to energy sources.
- Anatomically, cords like the spinal and vocal cords are essential for movement, sensation, and communication in the human body.
- The word also appears in fashion (corduroy) and as a unit of measurement for firewood (128 cubic feet).
At its most fundamental level, a cord is a flexible, multi-stranded length of material. Imagine several thin threads or fibers twisted or braided together to form a single, stronger unit. Unlike a single thread, which is delicate, or a heavy rope, which is bulky, a cord sits in the middle—strong enough to bind packages but thin enough to be manipulated easily by hand. In the modern world, the word has evolved significantly from its origins in textile manufacturing to become a ubiquitous term in electronics and anatomy.
- Physical Form
- A collection of twisted strands (hemp, nylon, or cotton) used for tying or pulling.
- Electrical Context
- An insulated wire equipped with plugs to connect an appliance to a power supply.
- Anatomical Context
- A part of the body resembling a string, such as the spinal cord or vocal cords.
"The mountaineer checked the strength of the nylon cord before beginning the descent."
The versatility of a cord lies in its tensile strength. Because it is made of twisted strands, it distributes weight and tension more effectively than a solid material of the same thickness. This is why we use 'cords' for window blinds, where constant pulling and friction would snap a simple string. In a digital age, we most frequently interact with 'power cords.' These are essentially the lifelines of our devices, carrying the electrical current from the wall outlet to the battery. Without this 'cord,' the device is effectively dead once its internal energy is depleted.
"Please don't trip over the extension cord running across the living room floor."
Beyond the physical, 'cord' appears in textiles as 'corduroy,' a fabric with raised parallel lines called 'wales' that look like small cords stitched together. In history, cords were used as symbols of office or rank, often braided with gold or silver thread and worn over the shoulder (known as an aiguillette). This shows that the word carries a weight of both utility and decoration. When we speak of 'cutting the cord,' we are using a powerful metaphor derived from the umbilical cord, signifying the moment of independence from a source of support or supply.
- Etymology
- Derived from the Greek 'khorde,' meaning 'string of a musical instrument' or 'intestine.'
"The surgeon was careful not to damage the spinal cord during the complex procedure."
In the realm of measurement, a 'cord' is also a unit of volume used for fuel wood. A standard cord of wood is a stack measuring 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet). This usage dates back to when wood was measured by tying a cord around the stack. Whether you are talking about the 'vocal cords' that allow you to speak or the 'bungee cord' that allows you to jump off a bridge safely, the concept remains the same: a flexible, strong, and essential link.
Using the word cord correctly depends heavily on the context—whether you are in a hardware store, a hospital, or an electronics shop. As a noun, it functions as the object of many common verbs related to connection, security, and power. To master its usage, one must understand the specific collocations that define its various roles in English.
- Verbs for Physical Cords
- Tie, bind, knot, fray, snap, unravel, weave, pull.
- Verbs for Electrical Cords
- Plug in, unplug, coil, tangle, fray, short-circuit, extend.
- Verbs for Anatomical Cords
- Strain (vocal cords), sever (spinal/umbilical), protect.
"You should unplug the cord by pulling the plug, not the wire itself, to prevent damage."
When describing a cord, adjectives often refer to its condition or its specific purpose. A 'frayed cord' is dangerous because the protective outer layer has worn away, exposing the inner strands or wires. A 'heavy-duty cord' is designed for high-stress environments or high-voltage appliances. In metaphorical use, 'the silver cord' is a literary term for the life-force connecting the soul to the body, while 'the umbilical cord' is frequently used to describe a dependency on a parent organization or country.
In technical writing, precision is key. If you are writing a manual, distinguish between a 'power cord' (supplies energy) and a 'patch cord' (transmits data). In medical writing, 'vocal cords' is the standard term, though 'vocal folds' is becoming more common in scientific circles. In everyday speech, if you ask someone for 'a cord,' they will likely assume you mean a charging cable for a phone. If you are in a garden, they will assume you mean twine or string for plants.
"The curtains are operated by a pull-cord located on the right side of the window frame."
Finally, consider the phrasal uses. To 'cordon off' an area (though spelled with an extra 'on') is related to the idea of using a cord or rope to create a boundary. To 'cord' wood is the act of stacking it into the specific measurement mentioned previously. Understanding these nuances ensures that your use of 'cord' is not only grammatically correct but also contextually appropriate for your audience.
The word cord is heard in a surprising variety of environments, ranging from the mundane to the life-altering. Because it spans technology, biology, and industry, you will encounter it in professional jargon as well as casual conversation. Recognizing these contexts helps in predicting the meaning of the word before the full sentence is even finished.
- In the Home
- Discussions about vacuum cleaner cords, phone chargers, and window blind repairs.
- In the Hospital
- Medical staff discussing the umbilical cord during birth or spinal cord injuries in neurology.
- In the Gym
- References to resistance cords or jump ropes (sometimes called speed cords).
"The tech support agent asked me to check if the power cord was securely seated in the port."
In the world of media and entertainment, 'cord-cutting' has become a dominant buzzword. This refers to the trend of consumers cancelling their traditional cable or satellite television subscriptions in favor of streaming services. Here, 'the cord' represents the physical coaxial cable that used to be the only way to receive television signals. When you hear a news report about 'cord-cutters,' they are talking about a massive shift in how society consumes information and entertainment.
In music, while the homophone 'chord' is more common, you might hear 'cord' in relation to equipment. A guitarist might complain about a 'bad cord' causing static in their amplifier. In sports like skydiving or bungee jumping, the 'cord' is the most discussed object, as it is the primary safety mechanism. Hearing 'pull the rip-cord' is a dramatic phrase often used in movies to signify a last-minute escape or a desperate measure to stop a fall.
"The singer had to cancel the tour due to inflammation of her vocal cords."
In industrial settings, you'll hear about 'cordage,' which is the general term for ropes and cords. Shipyards, construction sites, and warehouses use this term to describe their inventory of binding materials. Even in fashion, a designer might mention 'cord detail' on a jacket, referring to the decorative use of thin, braided material. The word is truly a linguistic chameleon, adapting its importance to the setting in which it is spoken.
Despite its simplicity, cord is frequently misused, primarily due to its phonetic similarity to other words and its overlap with related terms like 'wire' or 'string.' Avoiding these pitfalls is essential for clear communication, especially in written English where spelling distinguishes meaning.
- Cord vs. Chord
- 'Cord' is a string/wire. 'Chord' is a musical harmony or a geometric line segment.
- Cord vs. Wire
- A 'wire' is usually a single metal strand. A 'cord' is usually insulated or made of multiple strands.
- Vocal 'Cords' vs. 'Chords'
- It is always 'vocal cords' (anatomical strings), never 'vocal chords' (though they produce chords!).
"Incorrect: He played a beautiful cord on the guitar."
One common error is using 'cord' when 'cable' would be more appropriate in a technical context. While often interchangeable in casual speech, a 'cable' usually refers to a much thicker, more complex assembly (like a bridge cable or a heavy industrial power cable), whereas a 'cord' is thinner and more flexible. Using 'cord' for a massive suspension bridge support would sound strange to an engineer.
Another mistake involves the pluralization of 'vocal cords.' Some learners treat it as a singular entity ('my vocal cord is sore'), but humans have two, so it is almost always plural unless referring to a specific injury to just one. Additionally, in the context of 'corduroy' pants, people sometimes say 'my cords are dirty.' While correct in British English slang, it might be confusing in other regions where 'cords' would only mean electrical wires.
"Incorrect: The baby's umbilical chord was cut safely."
Finally, watch out for the phrase 'of one accord.' This uses 'accord' (meaning agreement), not 'a cord.' Saying 'they were all of one cord' is a common malapropism. Similarly, 'cordon' (as in 'cordon bleu' or 'cordon off') is related but has its own specific spelling and usage rules. By keeping the 'physical string' definition at the center of your mind, you can avoid most of these errors.
To truly understand cord, it helps to see where it sits in the hierarchy of 'long, thin things.' English has a rich vocabulary for connectors and binders, and choosing the right one adds precision to your descriptions. A 'cord' is more than a string but less than a rope.
- String
- Thinner and weaker than cord; used for light tasks like tying a bakery box.
- Rope
- Much thicker and stronger; used for towing cars or mooring ships.
- Twine
- A coarse, strong thread made of two or more strands twisted together, often used in gardening.
- Cable
- A very strong, thick rope made of wire or hemp, or an insulated bundle of wires.
"While a string might snap under the weight, a cord provides the necessary tension for the blind."
The distinction between 'cord' and 'wire' is particularly important in electronics. A 'wire' is a single conductor of electricity, usually made of copper or aluminum. A 'cord' is the finished product you buy—the wires inside plus the protective rubber or plastic insulation and the plugs at the ends. You wouldn't say 'I need a phone wire' as often as 'I need a phone cord' or 'charging cable.'
In the world of textiles, 'yarn' and 'thread' are the building blocks. If you twist enough yarn together, you get a 'cord.' In fashion, 'lace' (the kind used for shoes) is a type of cord. 'Braid' is another similar term, but it specifically refers to the method of construction (interweaving three or more strands) rather than just the final shape. 'Lanyard' is a specific type of cord worn around the neck to hold keys or ID cards.
"The sailor replaced the old twine with a durable nylon cord to secure the sails."
By comparing these words, we see that 'cord' implies a medium level of strength and a high level of flexibility. It is the 'Goldilocks' of the binding world—not too thin, not too thick, but just right for most daily tasks. Whether it's the 'drawstring' (a type of cord) in your hoodie or the 'extension cord' in your office, the word occupies a vital space in our descriptive toolkit.

よくある質問
10 問A cord is typically thinner and more flexible, often used for household appliances. A cable is usually thicker, more heavy-duty, and may contain multiple insulated wires or fibers. For example, you have a lamp cord but a bridge cable. In electronics, the terms are often used interchangeably. However, 'cable' is more common for data transmission.
It is always 'vocal cords.' This refers to the string-like anatomical structures in the larynx. While they produce musical 'chords' when you sing, the physical parts themselves are 'cords.' Using 'chords' is a very common spelling error. Always use the 'c-o-r-d' spelling for anatomy.
This is an idiom with two main meanings. Traditionally, it refers to a child becoming independent from their parents, like cutting the umbilical cord at birth. In modern times, it refers to cancelling a cable TV subscription to use streaming services. It symbolizes ending a dependency on a provider. It is a very common phrase in modern English.
A standard cord of wood is a stack that measures 128 cubic feet. This is usually 4 feet high, 4 feet wide, and 8 feet long. It is a traditional unit of measurement in the US and Canada. People buy wood by the cord for heating their homes in winter. It is important to check the dimensions when buying.
In fashion, 'cords' is a common shorthand for corduroy trousers. Corduroy is a durable fabric with a distinct ribbed pattern. These ribs are called 'wales.' The fabric looks like many small cords have been sewn together. It is a popular material for autumn and winter clothing.
Yes, 'cord' can be a verb, though it is less common. It means to tie or bind something with a cord. It can also mean to stack wood into cords. For example, 'He spent the afternoon cording the firewood.' In most cases, however, people use 'tie' or 'stack' instead.
Both are correct and commonly used. Most people say 'charging cord' or 'charging cable.' 'Cord' sounds slightly more casual, while 'cable' sounds slightly more technical. You will be understood regardless of which one you choose. In stores, they are often labeled as 'USB cables.'
An extension cord is a length of electrical power cable with a plug on one end and one or more sockets on the other. It allows you to use an appliance further away from a wall outlet. They come in various lengths and thicknesses. You should always use one that is rated for the power of your device. They are essential for home and office setups.
A bungee cord is an elastic cord composed of one or more elastic strands forming a core, usually covered in a woven cotton or polypropylene sheath. It is used to secure luggage or for the sport of bungee jumping. The elasticity allows it to absorb shock. It is also known as a shock cord. They are very useful for camping and transport.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain. It is part of the central nervous system. It transmits signals between the brain and the rest of the body. It is protected by the bones of the spine. Damage to it can be very serious.
