Some words just can’t be left alone. You can have a pair of glasses, climb the stairs, or dip into your savings, but try talking about just one "glass," (for your eyes) "stair," or "saving," and it suddenly feels a bit off. These traits go unnoticed most of the time, but they do exist. These 11 common words exist only in the plural form.
Glasses

It probably has to do with a pair of glasses having two separate pieces of glass, one for each eye. A similar element, but with a single glass, would be called a monocle.
Therefore, glasses only exist in their plural form, as only two make a complete set.
Clothes

The word "clothes" is always plural because it refers to multiple garments, not just one. Also, it differs from "cloth," which means the material.
Historically, "clothes" evolved from "cloths," once the plural of "cloth," which also meant a garment. As "cloth" shifted to mean just fabric, "clothes" kept their meaning as a collection of items like shirts, pants, or socks.
Scissors

A pair of scissors is composed of two blades, each with a handle attached to it, held together by a screw in the center. That is why it is called a pair of scissors and not just one scissors.
Theoretically, one could have a single scissor, meaning one blade, but it would not serve its natural purpose of cutting things by sliding the two blades together.
Stairs

The word "stairs_"_ is plural because it refers to a set or flight of steps, not just one. The structure involves multiple steps, making the plural form more natural in everyday use.
Yes, "stair" can appear in older texts or compound words like "staircase," but it’s less common and often refers to a single step or the entire flight. Still, most people use "stairs" to describe the full set.
Pants

Not unlike the previously mentioned glasses, "pants" are always plural because they come from pantaloons, which were originally two separate pieces: one for each leg. Even though modern pants are a single garment, the plural form stuck.
"Pants" is just a shortened form of "pantaloons," and the idea of two leg coverings helped keep the plural usage alive through habit and tradition.
Belongings

This one can seem tricky at first, since a person could, theoretically, own a single thing, but there is a logical explanation as to why it is a plural-only word. "Belongings" is plural because it refers to a collection of personal items someone owns, like clothes, books, or furniture. It implies more than one object, making the plural form natural.
The singular "belonging" has a different meaning altogether: it describes the feeling of being accepted or fitting in, not physical possessions.
Headphones

The word "headphones" is usually plural because it refers to a device with two earpieces worn on both ears. While "earphones" can describe the individual parts, the full set is commonly called "headphones."
Modern headphones are typically stereo and designed as a pair, which, in turn, reinforces the use of the plural form.
Species

The word "species" is used for both singular and plural forms, especially in biology. It comes from Latin, where the form was the same in both cases, which explains the modern usage.
In the world of taxonomy, "species" acts as a collective noun for organisms with shared traits.
Tongs

Similar to scissors, the word "tongs" is always plural because it describes a tool made of two connected parts that work together, just like scissors or pliers. This dual structure leads to the use of a plural noun, even for a single tool.
In English, tools with two joined parts are often plural nouns used only in the plural. It’s a common use born out of how these items are constructed and used.
Remains

A word with grim connotations, indeed, "remains" is usually plural because it refers to leftover parts or pieces of something, like uneaten food or human remains. Even when it’s one item, it’s seen as part of a whole that’s no longer intact.
It works as a collective noun, emphasizing the idea of multiple fragments. Though not strictly plural-only, it’s almost always used in the plural to reflect this meaning.
Savings

No one talks about "saving," meaning a collected amount of money. And that is because the word "savings" looks plural but can act as either a plural or a mass noun. For example, "significant savings" treats it as plural, while "the savings are substantial" treats it as a total amount.
As a mass noun, "savings" refers to the money saved overall, much like "money" itself. As it was seen in the previous examples, context determines whether it's treated as singular or plural.
