Q: Is "air" really a concrete noun if I can't see it?

Yes. A noun doesn't have to be visible to be concrete; it just has to be physically detectable . You can feel air (wind), smell its components (like ozone or pollutants), and measure its weight and pressure in a lab. If it is made of atoms, it is concrete.

Q: Are "music" and "noise" concrete nouns?

Yes. While you can't "grab" a sound wave, sound is a physical phenomenon that vibrates your eardrums. Because you can hear it (one of the five senses), "music," "thunder," and "alarm" are all concrete nouns.

Q: Are fictional things like "ghosts" or "unicorns" concrete?

Yes. Even though they don't exist in our reality, they are represented as having physical forms. If a unicorn existed, you could pet its fur and see its horn. Therefore, they are classified as concrete nouns because they describe a physical entity rather than an idea like "justice."

Q: What about "time"? Is a "clock" concrete but "noon" abstract?

Yes. Clock and calendar are concrete because they are physical objects. Time, years, and minutes are abstract because they are measurements of a concept. You cannot touch a "Tuesday," even if you can see the sun rise on one.

Question 3

Is a "dream" concrete or abstract?

Accepted Answer

Most grammarians classify dreams as abstract because they are a series of images and sensations created by the mind, rather than a physical object that others can see or touch. However, if you are talking about the biological brain activity (the REM cycle), you are moving into concrete territory.

Quick tip: A good rule of thumb from these grammarians is the "Senses Test." If you can't put the thing in a box or point to it so that a stranger sees exactly what you see, it’s usually abstract.
