Can you hyphenate a city's name?

Yes, you can hyphenate a city's name if it is officially recognized that way or if it helps clarify pronunciation or meaning. For example, names like "Kansas City" do not require a hyphen, but if a city's name includes a compound element that benefits from hyphenation for clarity, such as "San Fernando Valley," then hyphenation is appropriate. Always refer to official sources for the correct formatting of specific city names.
