What Are Common Nouns? [with Examples]

A common noun is the generic name for a person, place, or thing, e.g., boy, town, lake, bridge. Common nouns contrast with proper nouns, which are the given names [or titles] we give to things, e.g., Peter, New York, Lake Superior, London Bridge.

Common nouns are written with lowercase letters [unless they start a sentence], and proper nouns are written with uppercase letters.

Why Should I Care about Common Nouns?

Here are five noteworthy points related to common nouns and lowercase letters:

[Point 1] A common noun is not written with a capital letter unless it starts a sentence.

Do not be tempted to give a word a capital letter just because it's an important word in your sentence. In the following four examples, the words in bold are common nouns and should have lowercase letters.

We value our Clients' opinions.
Lisa, Vampires are make-believe, like elves, gremlins, and Eskimos.
[Homer Simpson]
We live in an age when Pizza gets to your home before the Police.

[Point 2] Write the seasons with lowercase letters.

The seasons are not written with capital letters unless they form part of a name.

This winter, I will spend a week at Winter Mountain River.
I booked a ticket for the Rhine Summer Ball last autumn.

Using a capital letter for a season is an understandable mistake given the days of the week [e.g., Monday, Tuesday] and months [e.g., January, February] are written with capitals. But, it's still a mistake.

[Point 3] Write the points of the compass with lowercase letters.

Do not use a capital letter for north, south, east, or west [i.e., the points of the compass] unless the word forms part of a name.

Take ten paces East and then dig.
To get to West Ham, go north then west.

Be aware though that geographical areas with names like The North, The South East, and The North West are proper nouns and written with capital letters.

I live in The East.

This issue can get a little more complicated. For example, should you write North Wales or north Wales? What about Central Europe and central Europe? Some would argue that as north Wales and central Europe are not recognized areas [they're certainly not well defined], then these terms are not titles [demanding all capital letters] but adjectives with titles [demanding lowercase adjectives]. An easy solution is to find a decent reference book about the area you're writing about and see what it says. If you can't do that, then you have several factors to consider:

How well the area is defined? [consider South Africa [well defined] and southern Africa [not well defined]]
How common is the term?
What would your readers expect?
How does each version look aesthetically when written?

If you're still unsure after all that thinking about it, go for the non-capitalized version [e.g., north Wales and central Europe]. You'll have fewer pedants on your case.

[Point 4] Write the Sun and the Moon with capital letters.

Our moon is called the Moon, and our sun is called the Sun. Therefore, the words to denote our moon and our sun can be either proper nouns or common nouns depending on context.

The moon orbiting Earth is called The Moon name of our moon] is a proper noun. That's why it has a capital letter.]
Are all suns as hot as The Sun?
The largest moon orbiting Jupiter is Ganymede.

This might help. Imagine you had a dog called Dog. It's the same issue.

I'm going to take the dog for a walk. Where is Dog's lead?

[Point 5] Write terms like Director and Claims Department with capital letters if they refer to specific people or departments.

With job titles and the names of departments particularly, it's sometimes unclear whether a term is a common noun or a proper noun. What's a company's claims department called? The Claims Department, I'd guess. So, it can be a common noun or a proper noun depending on context.

Treat such terms as proper nouns [i.e., treat them like titles and give them capital letters] when they refer to specific people or offices, otherwise use lowercase letters.

The President is my favourite president.
The Commanding Officer thought he'd never be a commanding officer.
I know my Dad is looking down on us. He�s not dead � just very condescending.
[Comedian Jack Whitehall]

Key Points

Don't give a word a capital letter just because it's an important word in your sentence.
The seasons and the points of the compass are written with lowercase letters [unless they're part of a name, i.e., part of a proper noun].
Our sun and moon are called The Sun and The Moon, which complicates things. This'll help [most of the time]: If they're preceded by the word the, give them a capital letter.
With terms like Mum, Director, and Finance Department, use capital letters when they refer to specific people or offices.
