Understanding when to use capitalization is a key aspect of elevating your written communication.

Capitalizing Sentences

Let’s start with the basics: capitalizing the first letter of every sentence. This fundamental rule sets the tone for clarity and professionalism in your writing. Remember to always capitalize the first word of every sentence, whether it’s a noun, verb, article, or preposition.

The sooner you accept a challenge, the quicker you can start to solve it.

We capitalize the first word of every sentence, whether that word is a noun, a verb, an article or a preposition.

Proper Nouns

Names of specific people, places, and things are considered proper nouns and should always be capitalized. This includes individuals, countries, cities, and brand names.

Note that we always capitalize “City” in the name of this particular city.

The CEO of Apple is Tim Cook.

We capitalize “Apple,” “Tim,” and “Cook” because they are all proper nouns.

Titles and Headings

When creating titles for your blog posts, articles, or any written work, capitalize the major words for clarity. Major words are any word that is not an article (“a,” “an,” or “the”) or a preposition (“of,” “from,” “to,” and “with,” for example).

Remember, we always capitalize the first word or a title, regardless of its part of speech. But after the first word, only capitalize the major words.
