Capitalize When Used as a Title
Capitalize "President" when it directly precedes a name and functions as a title, such as "President Biden" or "President of the Federal Reserve." This follows standard title capitalization rules in English.
Lowercase in Generic or Descriptive Use
Use lowercase "president" when the word is used descriptively or without a specific name, such as "the president spoke today" or "she became president of the company." Many style guides, including the Associated Press, recommend this approach.
Follow Style Guide Guidance
Major style guides differ slightly. The Chicago Manual of Style and AP Stylebook generally lowercase the word when it stands alone or is used descriptively. For more detail, see the Associated Press Stylebook guidance at https://www.apstylebook.com/basics/capitalization.
