IPA: /ˈkæpɪtəl/
KK: /ˈkæpɪtəl/
A building where a legislative body, such as a state or national government, meets to discuss and make laws.
The new capitol building was inaugurated last week, and it will host the state legislature's sessions.
Capitol is derived from the Latin word "capitoleum" (meaning temple of Jupiter), which is a diminutive form of "caput" (meaning head). The term originally referred to the temple on the Capitoline Hill in Rome, which was considered the head or center of Roman government. Thus, the word "capitol" signifies a building that serves as the seat of government, often where legislative assemblies meet.
Think of the 'head' ('caput') of government when you remember that a 'capitol' is a building where lawmakers gather.
