Sentence case, on the other hand, is a capitalization style that mainly uses lowercase letters. You can see examples of title case in our post on reference titles. This boils down to using lowercase only for “minor” words of three letters or fewer, namely, for conjunctions (words like and, or, nor, and but), articles (the words a, an, and the), and prepositions (words like as, at, by, for, in, of, on, per, and to), as long as they aren’t the first word in a title or subtitle.

Here are directions for implementing APA’s title case:
#WORD VS WORD CASE HOW TO#
Below are guidelines for when and how to use each case in an APA Style paper.

In both cases, proper nouns and certain other types of words are always capitalized. APA’s title case refers to a capitalization style in which most words are capitalized, and sentence case refers to a capitalization style in which most words are lowercased.

APA Style has two capitalization methods that are used in different contexts throughout a paper: title case and sentence case (see Publication Manual section 4.15).
