Word Nuance & Usage

Do not confuse 'capitol' with its homophone 'capital': 'capitol' (with an 'o') refers exclusively to a specific legislative building (easy to remember because the dome of a capitol is shaped like an 'o'), whereas 'capital' (with an 'a') refers to a city serving as a seat of government, financial wealth, or an uppercase letter.

Word Origin & Etymology

Borrowed from Old French Capitole and directly from Latin Capitolium, the great temple dedicated to Jupiter Optimus Maximus on the Capitoline Hill in ancient Rome, traditionally derived from caput ('head').
