Capital and Capitol: Which One to Use Where

What a pair these are: they sound identical and look nearly identical and both have meanings that relate to government. Mastering their use, however, is simple.

The key is this: capitol, the one with an "o," is very limited in use. It appears in the term Capitol Hill, and is used to refer to one very particular and famous building, to some other similar buildings, and, occasionally, to a group of buildings that includes those similar buildings. For all other meanings, the word you want is capital.

This means that in a state's capital city is a building or group of buildings properly referred to with the word capitol, with an "o." In this use capitol is synonymous with statehouse: both refer to the building or group of buildings where a state legislature meets. The phrase capital city utilizes capital because it refers to a city, not to a building or group of buildings.

Capitol with a capital "C" refers to the particular building in Washington, D.C. where the U.S. Congress meets. It often appears before other nouns in phrases like the Capitol building and Capitol police, and is very frequently used in the term Capitol Hill, which refers both to the legislative branch of the United States government as well as to the location of the Capitol building. The Capitol, like many state capitol buildings, has a rounded dome that is somewhat reminiscent of the top of an "o," which may help some remember the "o" spelling. Note that the word capital as used to describe an uppercase letter, like in the phrase capital "C", utilizes capital.

The word capital has three distinct homographs, two for noun uses and one for adjective uses. Readers should consult those entries for the various meanings of capital, but can be assured that they all end in al, rather than ol.

Word History

Etymology

Adjective

Middle English, "of the head, for the head (as a medication), chief, principal, (of a letter) larger than the other letters on the page (as an initial letter), deadly, mortal (of punishment, an enemy)," borrowed from Anglo-French & Medieval Latin; Anglo-French, "of the head, chief, large (of a letter), mortal (of a sin)," borrowed from Medieval Latin capitālis "of or for the head, mortal, entailing loss of life (of a penalty or offense), initial (of a letter), chief, principal (of a city or religious house)," going back to Latin, "entailing loss of life (of a punishment or crime), deadly, implacable (of an enemy)," from capit-, caput "head, source, leading person, chief city of a state or province, a person's life when endangered or the target of a curse, one's life as forfeit for a crime" + -ālis -al entry 1 — more at head entry 1

Note: As a derivative, classical Latin capitālis reflects only extended senses of caput, as a metonym for a human life in regard to its exposure to danger or to forfeiture as a punishment; capitālis in the literal meaning "of the head" is only attested in post-classical Latin.

Noun (1)

(sense 1) borrowed from Italian capitale "real or monetary assets, personal or corporate wealth," going back to Medieval Latin capitāle "movable property, riches," noun derivative from neuter of capitālis "of the head, chief, principal"; (sense 2) derivative of capital entry 1 (sense 1), after Middle French capitale (by ellipsis from lettre capitale) or Medieval Latin capitālis (by ellipsis from littera capitālis); (sense 3) derivative of capital entry 1 (sense 2a), after Middle French capitale (by ellipsis from ville capitale) — more at capital entry 1

Note: The Italian word capitale was diffused into other western European languages due to the European significance of the Florentine banking houses. The meaning "movable property, patrimony, riches" of capitāle is attested in Latin from the ninth century (in the half-vernacular form catallum, from Chartres) and in Romance vernaculars: in the Gallo-Romance area (Old French chatel, in the dialect of Picardy and French Flanders catel—see cattle, chattel; as Old Occitan capdal), in Iberia (Spanish caudal "property, abundance"), northern Italy (Upper Italian cavear [Genoa] "patrimony in money, riches," cavià [Asti], cavedale [Milan]—see Lessico etimologico italiano); in Tuscany, capitale. The semantic logic behind a derived nominal sense "property" from an adjectival sense "of the head, chief, principal" (if these are even the relevant meanings) is less than transparent. Note, however, the use of caput to mean "head of cattle," a form of wealth, in the early Germanic laws (Lex Salica, Lex Allamanorum—see Niemeyer, Mediae Latinitatis lexicon minus).

Noun (2)

Middle English capitale, borrowed from Anglo-French capital, capitel, borrowed from Late Latin capitellum, from Latin capit-, caput "head" + -ellum, neuter of -ellus, diminutive suffix, originally with noun stems ending in -ul-, -r- and -n- — more at head entry 1
