Latin-derived Numerical Names

This section contains weasel words: vague phrasing that often accompanies biased or unverifiable information. Such statements should be clarified or removed.

Latin terms for anniversaries are mostly straight forward, particularly those relating to the first twenty years (1-20), those relating to multiples of ten years (30, 40, 60, 70 etc.), and those relating to multiples of centuries or millennia (100, 200, 300, 1000, 2000, 3000 etc.) In these instances, the anniversary generally comes from a derivative of the Latin word for the respective number of years. However, when anniversaries relate to fractions of centuries (125, 150, 175, 250 years - i.e., 1.25, 1.5, 1.75, and 2.5 centuries), the situation is not as simple.

Roman fractions were based on a duodecimal system. From 1/12 to 8/12 they were described as multiples of twelfths (uncia "twelfth"; the source of the English words inch and ounce) and from 9/12 to 11/12 they were described as multiple-twelfths less than the next whole unit - i.e., a whole unit less 3/12, 2/12 or 1/12 respectively. There were also special terms for quarter (quadrans), half (semis), and three-quarters (dodrans). Dodrans is a Latin contraction of de-quadrans which means "a whole unit less a quarter" (de means "from"; quadrans means "quarter". Thus for the example of 175 years, the term is a quarter century less than the next whole (bi)century or 175 = (-25 + 200).

In Latin it seems that this rule did not apply literally for 1½. Whereas "secundus" is Latin for "second", or "bis" for "twice" these terms are not used such as in sesqui-secundus. Instead just sesqui (or ses) is used by itself. This may be because it relates to a ratio of one - thus it means "and a half" compared to "one". (It may also be because 1/8 in Latin is sescuncia, sescunciae (from sesqui- + uncia, i.e., 1½ uncias) defined as one-and-a-half twelfths (3/2 × 1/12 = 1/8).)

60 years Sexagennial / Sexagenary Diamond Jubilee of monarchs
70 years Septuagennial Platinum Jubilee of monarchs
75 years Dodranscentennial Diamond Jubilee Dodrans is a Latin contraction of de-quadrans which means "a whole unit less a quarter" (de means "from"; quadrans means "quarter". 75 years is a quarter century less than a whole century or 75 = (-25 + 100).
Dodracentennial Alternative Latin form of Dodranscentennial
Dequascentennial Alternative Latin form of Dodranscentennial
Semisesquicentennial Probably a modern coined term. Demisesquicentennial or Hemisesquicentennialis are other similar variants.
100 years Centennial Centenary / platinum jubilee
125 years Quasquicentennial Term is broken down as quasqui- (and a quarter) centennial (100 years). Quasqui is a contraction from quadrans "a quarter" plus the clitic conjunction -que "and". The term was coined by Funk and Wagnalls editor Robert L. Chapman in 1961.
150 years Sesquicentennial Term broken down as sesqui- (one and a half) centennial (100 years)
175 years Dodransbicentennial - Dodrans is a Latin contraction of de-quadrans which means "a whole unit less a quarter" (de means "from"; quadrans means "quarter". 175 years is a quarter century less than the next whole (bi)century or 175 = (-25 + 200).
Dodrabicentennial Alternative Latin form of Dodransbicentennial
Dequasbicentennial Alternative Latin form of Dodransbicentennial
Dosquicentennial Dosquicentennial has been used in modern times and this is perhaps a modern contraction of "de-quadrans". However, it seems inappropriate to combine the terms que and de when dealing with such Roman fractions. In any event, if such a conjunction was appropriate then it would perhaps more likely have been "Dosquibicentennial" (but the result is little shorter anyway).
Demisemiseptcentennial Probably a modern coined term: demisemiseptcentennial; literally one-half (demi-) x one-half (semi-) x seven (sept-) x 100 years (centennial)—also demisemiseptcentenary.
Quartoseptcentennial Probably a modern coined term: quartoseptcentennial; literally one-quarter (quarto-) x seven (sept-) x 100 years (centennial)—also quartoseptcentenary.
Terquasquicentennial First used by Bell Laboratories in celebrating its 175th anniversary as a corporation. Is a coined word for an anniversary of 175 years, but the elements of the word literally refer to an anniversary of 375 years, as follows: ter- (3) × quasqui- (1¼) × centennial (100 years)
Septaquintaquinque-
centennial
Suggested by lexicographer Robert L. Chapman to William Safire; first appeared in Safire's column, "On Language" (The New York Times Magazine, February 12, 1995). It is a coined word for an anniversary of 175 years, but the elements of the word literally refer to an anniversary of 35,000 years, as follows: septaquinta- (70) × quinque- (5) × centennial (100 years)
200 years Bicentennial
250 years Sestercentennial - To express 2½ in Latin it would be expressed as "half-three". The term relates to being halfway to the third integer. In Latin this is "Sestertius" which is a contraction of semis (halfway) tertius (third) - hence Sestercentennial.
Semiquincentennial Probably a modern coined term: semi- (half) × quin (5) × centennial (100 years) = 250 years
Bicenquinquagenary Used by Princeton University in 1996, Reading, Pennsylvania in 1998, and Washington and Lee University in 1999. It is a coined word for an anniversary of 250 years, but the elements of the word literally refer to an anniversary of 10,000 years, as follows: bi- (2) × cen(t)- (100) × quinquagenary (50 years)
Quarter-millennial Meaning one fourth of one thousand years.
300 years Tercentennial Tricentennial
350 years Sesquarcentennial - A modern coined term; sesquarcentennial for 350 years is deduced here from the "Sestertius" definition for 250 years above. For 350 years it relates to being halfway from the third to the fourth integer; thus a contraction of semis (halfway) and quartus (fourth); hence Sesquarcentennial.
Semiseptcentennial Probably a modern coined term: semi- (half) × sept(7) × cen(t)- (100) × centennial (350 years)
400 years Quadricentennial Quatercentenary
500 years Quincentennial
600 years Sexcentennial
700 years Septcentennial Septuacentennial Probably a coined term; earliest known use in March 1988. Chiang Mai Septcentennial Stadium (Chiang Mai, Thailand) was completed in 1991.
800 years Octocentennial
900 years Nonacentennial
1000 years Millennial
2000 years Bimillennial

Famous quotes containing the words numerical and/or names:

    The moment a mere numerical superiority by either states or voters in this country proceeds to ignore the needs and desires of the minority, and for their own selfish purpose or advancement, hamper or oppress that minority, or debar them in any way from equal privileges and equal rights—that moment will mark the failure of our constitutional system.
    Franklin D. Roosevelt (1882–1945)

    No, no! I don’t, I don’t want to know your name. You don’t have a name, and I don’t have a name, either. No names here. Not one name.
    Bernardo Bertolucci (b. 1940)
