glass
A glass is a clear container you drink from, or the hard material used for windows.
Explanation at your level:
A glass is a cup. You use it to drink water, juice, or milk. It is clear and you can see through it. Please be careful because a glass can break if it falls on the floor!
We use the word glass for two things. One is the material in our windows. The other is the container we use to drink. For example, 'I need a glass of water.' If you have more than one container, you have two glasses.
The word glass is very common. As a material, it is uncountable. You can say 'This bottle is made of glass.' As a container, it is countable. You can say 'Could you pass me a glass?' It is important to remember the plural form 'glasses' when you are talking about cups or even the item you wear to see better.
Beyond the literal meaning, glass is often used in metaphorical contexts. We talk about a 'glass ceiling' in business or 'shattered dreams' like broken glass. It is a versatile noun that fits into both technical discussions about architecture and casual social interactions like 'raising a glass' to a friend.
In advanced English, glass can signify fragility or transparency. Writers often use it to describe delicate situations or people who are 'glass-like' in their emotional vulnerability. It also appears in technical contexts, such as 'fiber optics' or 'borosilicate glass' in scientific research, showing how a simple noun can span from daily life to complex engineering.
Historically and culturally, glass represents a pinnacle of human craftsmanship, transitioning from a rare luxury to a ubiquitous utility. In literature, it often serves as a symbol of clarity, memory, or the passage of time—think of the 'hourglass.' Understanding its nuance requires recognizing both its physical properties and its deep-seated metaphorical weight in Western thought.

Hey there! Let's talk about the word glass. It is a super common word that plays two main roles in our language. First, it refers to the material itself—that smooth, hard, and transparent stuff that lets light pass through. You see it in windows, eyeglasses, and smartphone screens.
Second, we use it to describe a drinking vessel. If you are thirsty, you might reach for a glass of water. Even if the cup is made of plastic or metal, people often still call it a 'glass' if it is shaped like one! It is a very versatile word that you will hear every single day.
The word glass comes from the Old English word glæs, which meant 'glass' or 'amber.' It is part of the Germanic language family, sharing roots with the Old High German word glas. Interestingly, it is related to the word 'glow' or 'gleam,' which makes sense because glass is shiny and reflects light!
Humans have been making glass for thousands of years, with early evidence dating back to ancient Mesopotamia and Egypt. It was once considered a luxury item, almost as valuable as precious gems. Over centuries, the manufacturing process evolved from simple beads to the massive sheets of architectural glass we see in modern skyscrapers today.
In English, glass is usually a mass noun when talking about the material, and a count noun when talking about the drinking container. You can say 'The table is made of glass' (material) or 'I broke two glasses' (containers).
Common collocations include shattered glass, stained glass, and a glass of water. The register is neutral, meaning you can use it in a casual chat with friends or in a formal report about construction materials without sounding out of place.
Idioms are fun ways to use this word! 1. Glass ceiling: An invisible barrier that stops people from reaching high positions. 2. People in glass houses shouldn't throw stones: Don't criticize others if you have the same flaws. 3. Look at the world through rose-colored glasses: To see things as better than they really are. 4. Raise a glass: To toast someone at a celebration. 5. Glass jaw: Used in boxing to describe someone who is easily knocked out.
The plural of the container is glasses, but the material 'glass' does not have a plural form. In terms of pronunciation, the British IPA is /ɡlɑːs/ while the American IPA is /ɡlæs/. The stress is on the single syllable.
It rhymes with words like pass, grass, class, mass, and brass. Remember that when referring to the material, you don't use 'a' or 'an' before it unless you are describing a specific type, like 'a tempered glass.'
