[1] Federal (adj.) 1640s, as a theological term (in reference to "covenants" between God and man), from French fédéral, an adjective formed from Latin foedus (genitive foederis) "covenant, league, treaty, alliance," from PIE *bhoid-es-, from root *bheidh- "to trust" (which also is the source of Latin fides "faith;" see faith).
Secular meaning "pertaining to a covenant or treaty" (1650s) led to political sense of "formed by agreement among independent states" (1707), from use of the word in federal union "union based on a treaty" (popularized during formation of U.S.A. 1776-1787) and like phrases. Also from this period in U.S. history comes the sense "favoring the central government" (1788) and the especial use of the word (as opposed to confederate) to mean a state in which the federal authority is independent of the component parts within its legitimate sphere of action. Used from 1861 in reference to the Northern forces in the American Civil War.
Federation (n.) 1721, "union by agreement," from French fédération, from Late Latin foederationem (nominative foederatio), noun of action from Latin foederare "league together," from foedus "covenant, league" (see federal).
Confederation (n.) early 15c., "act of confederating," from Middle French confédération, from Old French confederacion (14c.), from Late Latin confoederationem (nominative confoederatio), noun of action from confoederare (see confederate). Meaning "states or persons united by a league" is from 1620s.
[2] Unite (v.) early 15c. (transitive), from Late Latin unitus, past participle of unire "to unite, make into one" (transitive), from Latin unus "one" (see one). Intransitive sense from 1610s. Related: United; uniting.
[3] State (n.) : "political organization of a country, supreme civil power, government," c. 1300, from special use of state (n.1); this sense grew out of the meaning "condition of a country" with regard to government, prosperity, etc. (late 13c.), from Latin phrases such as status rei publicæ "condition (or existence) of the republic." c. 1200, "circumstances, position in society, temporary attributes of a person or thing, conditions," from Old French estat "position, condition; status, stature, station," and directly from Latin status "a station, position, place; way of standing, posture; order, arrangement, condition," figuratively "standing, rank; public order, community organization," noun of action from past participle stem of stare "to stand" from PIE root *sta- "to stand" (see stet). Some Middle English senses are via Old French estat (French état; see estate). The Latin word was adopted into other modern Germanic languages (German, Dutch staat) but chiefly in the political senses only. Meaning "physical condition as regards form or structure" is attested from late 13c. Meaning "mental or emotional condition" is attested from 1530s (phrase state of mind first attested 1749); colloquial sense of "agitated or perturbed state" is from 1837.
