ann-, anni-, annu-
(Latin: year, yearly)
2. A celebration or other commemorative ritual marking the date of an important event.
3. Etymology: from Latin anniversarius, "returning annually", from annus, "year" + versus; past participle of vertere. "to turn". The adjective came to be used as a noun in Church Latin as anniversaria dies with reference to saints' days.
The year rolls around to bring the anniversary of birth, marriage, or some other event; and this "turning" of the year is the literal meaning of the word anniversary.
Some people translate anno Domini as "in the year of our Lord", but there is no Latin noster, "our", in the phrase. A.D. is written before the year, usually with small capital letters, with no separating comma, as: A.D. 1995; or informally, after the year, as: about 1450 A.D. Anno Domini is supposed to indicate the number of years from the birth of Chirst.
In the sixth century, Dionysius Exiguus initiated the system of expressing dates by referring events to the birth of Christ. According to his calculations, Christ was born in 754 A.U.C. (abbreviation, ab urbe condita; from [since] the founding of the city [Rome], c. 753 B.C.); however, it is generally agreed that Christ was born at least four years before the date that was set by Dionysius.
The Irish theologian, Ussher, in the mid-seventeenth century computed the date of creation as 4004 B.C therefore, the year A.D. 2000 corresponds to 5761 A.M. or 6004 A.M., depending on whose date of creation one might prefer.
2. A plant that lives for only one year or season: "We planted some annual flowers in front of the house."
3. A book or magazine that is published once a year: "We just received the annual publication about new words which have been created this year."
2. Lasting indefinitely; perpetual, continual: "She sits there with that perennial grin on her face."
3. In botany, having a life span of more than two years; such as, a perennial plant: "There are many perennial plants that produce flowers every year."
