Types of Noun

The 4 simple noun groups are: person, place, thing or idea. Let's take a look at these:

People have names, and they're always written with a capital letter.
e.g. John, Heather, James, Henrietta, etc.

Everything has a name, but things can also include groups.
e.g. herd (of cows), class (of children), platoon (of troops).

Specific, unique places - such as towns and cities - have names.
e.g. Wellington or Manchester.
Like people, they start with capital letters.

Some places are more general and can be found anywhere.
e.g. the park or the airport.

Ideas are not objects, but can still be considered a thing.
e.g. anger, fear, truth, beauty, happiness, love.
