Do You Capitalize Dad in Writing?

Last Updated

Is “dad” capitalized?  

The answer is it depends on whether dad is used as a proper noun or a common noun in the text. As a proper noun, “Dad” should be capitalized. As a common noun, dad uses lowercase letters. First, let’s understand a couple of basic rules about grammar, the difference between proper nouns and common nouns, and when to capitalize—in the following section.

Back to the basics: proper nouns vs common nouns

One of the main capitalization rules in English grammar is that all proper nouns are capitalized, no matter where they appear in a sentence. Proper nouns name specific people, places, things, or ideas. A person’s name is a proper noun, and so is the name of a country or company. That said, simply writing ‘country’ or ‘company’, does not require these words to take on a capital letter.

This is because they are common nouns: they refer to a general category or type of thing and do not point out a specific thing or entity. This chart shows the difference between both common and proper noun forms:
