Many decisions about whether or not to capitalize words involve knowing the difference between proper and common nouns. Common nouns name a general person, place, or thing; however, proper nouns name a specific person, place, or thing.
Common nouns begin with lowercase letters (woman, city, soft drink), while proper nouns begin with capital letters (Norah, Dublin, Dr. Pepper). Common nouns can be singular or plural, while most proper nouns are singular. Another way to distinguish common from proper nouns is to look at the words before the noun. Common nouns are almost always preceded by articles and determiners, while proper nouns seldom are. This means you can write “that woman,” “our city,” or “my soft drink.”
On the other hand, Norah refers to a single girl, Dublin a single city, and Dr. Pepper a specific thirst quencher. Of course, English is a language of exceptions. Occasionally you need determiners with proper nouns. For example, there may be more than one Norah in the room (that Norah), more than one city by the same name (the [pronounced “thee”] Dublin in Texas), or more than one soda can on the counter (my Dr. Pepper).
The name your parents gave you at birth is a proper noun, as are a number of details about how you got your start. To tell your unique story, you need to use proper nouns. Capital letters are sprinkled throughout memoirs, personal narratives, and autobiographies. A story of a girl who grew up in a Texas town sounds humdrum. However, if a girl named Norah grew up in in a brick house close enough to the Dublin Bottling Works to smell the Dr. Pepper, you read details that help you envision a unique person.
