capital / capitol
The words capitol and capital seem to be very similar, but they are from different Latin roots.
The more general term, capital, has various senses, meaning punishable by death, principal, a seat of government, and wealth used in an investment. It first appears in Middle English in the 13th century and comes, via Old French, from the Latin capit?lus. The Latin root, caput, means head or money paid out. (This Latin root is unrelated to the German kaputt, meaning broken.)
