Capitalization

Consult a dictionary to determine the normal capitalization for most words. For a list of dictionaries, see Reference Works .

For information on specific capitalization schemes, see the following sections:

In Text

Capitalize proper nouns (personal names, geographical names, organizations, etc.). However, many terms that are derived from or associated with proper nouns are not capitalized. See The Chicago Manual of Style for more detailed information.

President A. B. Cee of XYZ Corporation
but A. B. Cee, president of XYZ Corporation

English standard units
but
plaster of paris

U.S. Department of Defense
but executive branch of the federal government

The official names of departments, projects, and programs should be capitalized appropriately.

University and National Laboratory Programs department
Law department
Partnering for Total Quality program
Point-of-Use Ultrapure Water Monitoring project

Titles

Capitalize the first letter of the first word and other significant words in a title. Do not capitalize the following:

  • Articles (a, an, the)
  • Conjunctions (and, but, or)
  • Prepositions of fewer than five letters (in, with, for)
  • The to in an infinitive

In a hyphenated compound, capitalize the second element if it is NOT a four-letter preposition.
