As we’ve already learned, a noun is the name of a person (Dr. Sanders), place (Lawrence, Kansas, factory, home), thing (scissors, saw, book), or idea (love, truth, beauty, intelligence).
Let’s look at the following examples to get a better idea of how nouns work in sentences. All of the nouns have been bolded in blue:
- The one experiment that has been given the most attention in the debate on saccharin is the 1977 Canadian study done on rats.
- The Calorie Control Council, a group of Japanese and American manufacturers of saccharin, spent $890,000 in the first three months of the 1977 ban on saccharin on lobbying, advertisements, and public relations.
- A flat-plate collector located on a sloping roof heats water which circulates through a coil and is pumped back to the collector.
- The blades start turning when the windspeed reaches 10 mph, and an anemometer is attached to the shaft to measure windspeed.
- The multi-fuel capacity of the Stirling engine gives it a versatility not possible in the internal combustion engine.
- The regenerative cooling cycle in the engines of the Space Shuttle is made up of high pressure hydrogen that flows in tubes connecting the nozzle and the combustion chamber.
Types of Nouns
Of the many different categories of nouns, a couple deserve closer attention here.
Common vs. Proper Noun
vs.
Common nouns are generic words, like tissue. They are lower-cased (unless they begin a sentence). A proper noun, on the other hand, is the name of a specific thing, like the brand name Kleenex. Proper nouns are always capitalized.
- common noun: name
- proper noun: Ester
Concrete vs. Abstract Noun
vs. 
Concrete nouns are things you can hold, see, or otherwise sense, like book, light, or warmth.
Abstract nouns, on the other hand, are (as you might expect) abstract concepts, like time and love.
- concrete noun: rock
- abstract noun: justice
The rest of this section will dig into other types of nouns: count v. non-count nouns, compound nouns, and plural nouns.
