A zipper is a common tool you find on clothes, like jackets or pants, and also on bags.
It works by having two lines of small teeth, made of metal or plastic.
A special slider piece moves up or down, making these teeth connect or separate.
This creates a fast and safe way to close or open two parts of fabric, keeping things secure inside a bag or making your clothes fit well.
A zipper, fundamentally, is a sophisticated fastening mechanism integral to contemporary apparel and various utility items. It comprises two flexible strips, each embedded with interlocking teeth, typically crafted from metal or plastic, which are precisely engaged or disengaged via a movable slider. This ingenious design facilitates the rapid and secure conjoining or separation of fabric edges, offering a more efficient alternative to traditional buttons or laces. Its ubiquity stems from its reliability, ease of use, and ability to create a seamless closure, enhancing both the functionality and aesthetic appeal of garments and accessories.
A zipper, fundamentally, is an ingenious mechanical contrivance designed for the facile and secure juxtaposition of two discrete fabric edges.
Its operational paradigm hinges on the interlocking engagement of two parallel series of protuberances—typically fashioned from metal or a durable polymer—which are progressively brought into alignment and subsequently disengaged by the reciprocal translatory motion of a sliding element.
This ubiquitous fastening mechanism affords a high degree of structural integrity and practical utility across a diverse spectrum of applications, ranging from apparel to various forms of containment.
The inherent efficiency of its design allows for rapid manipulation, thereby facilitating both the expeditious closure and opening of garments or receptacles.
§ What Does 'Zipper' Mean?
- DEFINITION
- A zipper is a mechanical device primarily used for fastening two edges of fabric or other flexible material together. It consists of two rows of interlocking teeth, typically made of metal or plastic, which are opened or closed by a sliding piece called a slider. The slider moves up and down, engaging or disengaging the teeth to create a secure closure or an opening.
The term 'zipper' is derived from the 'zip' sound it often makes when being opened or closed quickly. It's a highly functional invention that revolutionized how clothes and bags are designed and used, offering a much faster and more secure alternative to buttons, laces, or hooks.
§ When Do People Use a Zipper?
Zippers are ubiquitous in everyday life due to their versatility and efficiency. They are primarily used for:
- Clothing: Zippers are an integral part of various garments.

使い方
When using 'zipper,' remember that it can function as both a noun and a verb. As a noun, it refers to the fastening device itself. For example: 'My jacket has a broken zipper.' As a verb, it describes the action of closing or opening with a zipper: 'Please zipper up your coat; it's cold outside.'
A common mistake is confusing 'zipper' with similar fastening devices, such as 'buttons' or 'snaps.' While they all serve to fasten, a zipper specifically refers to the interlocking teeth mechanism. Another error can be using 'zipper' incorrectly as an adjective when 'zipped' or 'zippered' would be more appropriate. For example, instead of 'a zipper bag,' it's better to say 'a zippered bag' or 'a bag with a zipper.'

よくある質問
10 問A zipper is a device that fastens clothes or bags. It has two rows of teeth, made of metal or plastic, and a sliding piece that pulls them together to join two edges of fabric. It's a quick and secure way to close things.
Yes, there are! You can find zippers made with metal teeth, which are often stronger, or plastic teeth, which can be more flexible and sometimes lighter. The type of material can depend on what the zipper is used for.
You'll find zippers on lots of everyday items! Think about your jeans, jackets, backpacks, purses, and even some boots. They're really common for fastening clothes and bags securely.
If a zipper is stuck, sometimes a little bit of graphite from a pencil or a small amount of soap rubbed on the teeth can help it move more smoothly. Gently wiggling it can also sometimes free it.
Zippers offer a continuous and often quicker way to fasten things compared to buttons, which require individual buttonholes. Zippers generally provide a more secure and seamless closure.
Like any mechanical part, zippers can break, especially if they are used roughly or if a tooth gets bent. However, good quality zippers are designed to be quite durable and last a long time.
Both terms are commonly used! In British English, 'zip' is often used as both a noun and a verb, while in American English, 'zipper' is the more common noun. They refer to the same thing.
The word 'zipper' is thought to come from the sound it makes when it opens and closes—a 'zip' sound. It was coined in the early 20th century.
It's possible to replace a broken zipper yourself, especially for simpler items, but it can be a bit tricky and might require some sewing skills. For more complex items, you might want to take it to a tailor or a repair shop.
While some specialized zippers are designed to be water-resistant or even waterproof, most standard zippers are not completely waterproof. Water can still get through the small gaps between the teeth, especially in heavy rain.

Well written! Good try! Check the sample answer below.
Sample answer
The humble zipper, a seemingly mundane fastening device, often transcends its utilitarian origins to become a powerful symbolic motif in art and fashion. Its inherent action of opening and closing lends itself readily to metaphors of revelation and concealment, or even connection and disconnection. In fashion, a prominent zipper can signify edginess or rebellion, while in art, it might represent a societal 'unzipping' of truth or a metaphorical 'fastening' of ideology. This transformation from practical object to symbolic device highlights how cultural contexts imbue ubiquitous items with profound, often unforeseen, meanings.
Imagine a dystopian future where 'zippers' are considered a luxury item, meticulously crafted and heavily taxed, accessible only to the elite.

Well written! Good try! Check the sample answer below.
Sample answer
In a dystopian future where zippers are a guarded luxury, accessible solely to the elite, the societal implications would be profound and pervasive. This restriction would exacerbate socioeconomic stratification, making the simple act of securely fastening clothing a stark indicator of privilege. The general populace would resort to archaic or less efficient fastening methods, such as ties, buttons, or even permanent stitching, leading to practical inconveniences and a tangible sense of inferiority. The 'zipper' would transform from a convenience into a potent symbol of status and control, deepening the chasm between the privileged few and the disenfranchised masses, and subtly reinforcing the omnipresent power structures.
