Capitalization

Capitalization rules are numerous and quite often challenging. This discussion focuses on the most basic rules used in capitalization. Consider the following examples:

Incorrect: The king of Persia was assassinated.

Incorrect: The courses in English are challenging, but the courses in Mathematics are impossible.

Rule To Remember

Capitalize the first word of a sentence, unique people, places, or things.

Correcting the Problem

In the first sentence, the word King refers to a unique title and it, therefore, needs to be capitalized. In the second sentence, mathematics refers to a general subject and not a specific course. It needs to be in lower case.

Correct: The King of Persia was assassinated.

Correct: The courses in English are challenging, but the courses in mathematics are impossible.

The most general rule for capitalization is to use capital letters always:

  • To begin a sentence
  • For unique people, places, or things
  • For some abbreviations

Correct: Considering economic differences between North and South, the Civil War was inevitable.

Capitalization in Sentences

Always begin sentences with a capitalized word. This may mean changing numerals to letters:

Correct: One hundred and thirty-five votes were needed to win the election.

Correct: Nineteen Eighty-Four was written by George Orwell.

Capitalization rules also apply to excerpts and quotations when you adapt these to begin a sentence. Here is one example:

[Line as it appears in the text]:

Correct: But Mario couldn't deliver my note as no one really knows to this day where Lio is.

[As it appears when included in your paper at the beginning of a sentence]:

Correct: 'No one really knows to this day where Lio is' serves to affirm the author's reality, that Lio is yet another victim of the dictator's cruel and motiveless inhumanity.

But when a sentence is broken up into fragments for emphasis, subsequent parts are not capitalized:

Correct: What should I do? stay? or leave?
