Capitalization After Colons
by David Becker
One basic rule of APA Style is to capitalize the first word after the colon in a title. For example, in the movie title Superman IV: The Quest for Peace, the is capitalized because it is placed directly after the colon. The same would be true for titles in a reference list where only the first word, proper nouns, and the first word after a colon or an em dash should be capitalized. Here’s an example:
Braucher, D. (1998). Darth Vader vs. Superman: Aggression and intimacy in two preadolescent boys' groups. Journal of Child & Adolescent Group Therapy, 8(3), 115–134. doi:10.1023/A:1022936202071 |
The first word directly after a colon that begins an independent clause should also be capitalized. For example, one would write, “There is a valuable lesson to be learned in The Princess Bride: One should never get involved in a land war in Asia.” However, if the sentence were reworked to say, “The Princess Bride teaches us the most famous of the classic blunders: getting involved in a land war in Asia,” then getting is not capitalized because the clause directly after the colon cannot stand on its own as an independent clause.
Occasionally, a numbered or bulleted list follows a colon. The same basic rules described above apply to these situations. To learn more, read our previous blog posts about numbered lists and bulleted lists.
