accretion1. Botany the growing together of normally separate plant or animal parts 2. Pathola. abnormal union or growing together of parts; adhesion b. a mass of foreign matter collected in a cavity 3. Law an increase in the share of a beneficiary in an estate, as when a co-beneficiary fails to take his share 4. Astronomy the process in which matter under the influence of gravity is attracted to and increases the mass of a celestial body. The matter usually forms an accretion disc around the accreting object 5. Geology the process in which a continent is enlarged by the tectonic movement and deformation of the earth's crust accretion (aggregation) The increase in mass of a body by the addition of smaller bodies that collide and stick to it. The relative velocity of any two colliding bodies must be low enough for them to coalesce on impact rather than fly apart. Once a large enough body forms, its gravitational attraction accelerates the accretion process. Accreting objects in the Universe are numerous and diverse. They include protoplanets, protostars, black holes, and X-ray binaries. The accretion process is thought to occur generally in the form of a disk. Accretion is now assumed to have had an important role in the formation of the planets from swarms of dust grains. In the outer Solar System the grains were like dirty snowflakes and thus accretion was accelerated. See Solar System, origin.accretion[ə′krē·shən] (astronomy) A process in which a star gathers molecules of interstellar gas to itself by gravitational attraction. (civil engineering) Artificial buildup of land due to the construction of a groin, breakwater, dam, or beach fill. (geology) Gradual buildup of land on a shore due to wave action, tides, currents, airborne material, or alluvial deposits. The process whereby stones or other inorganic masses add to their bulk by adding particles to their surfaces. Also known as aggradation. accretion tectonics (meteorology) The growth of a precipitation particle by the collision of a frozen particle (ice crystal or snowflake) with a supercooled liquid droplet which freezes upon contact. accretion
accretion [ah-kre´shun] 1. growth by addition of material.2. accumulation.adherence of parts normally separated.ac·cre·tion (ă-krē'shŭn), 1. Increase by addition to the periphery of material of the same nature as that already present; for example, the manner of growth of crystals. Synonym(s): accrementition (2) 2. In dentistry, foreign material (usually plaque or calculus) collecting on the surface of a tooth or in a cavity. 3. A growing together.

AccretionThe act of adding portions of soil to the soil already in possession of the owner by gradual deposition through the operation of natural causes. The growth of the value of a particular item given to a person as a specific bequest under the provisions of a will between the time the will was written and the time of death of the testator—the person who wrote the will. Accretion of land is of two types: (1) by alluvion, the washing up of sand or soil so as to form firm ground; and (2) by dereliction, as when the sea shrinks below the usual watermark. The terms alluvion and accretion are often used interchangeably, but alluvion refers to the deposit itself while accretion denotes the act. Land uncovered by a gradual subsidence of water is not an accretion; it is a reliction. accretion 1 the natural increase in the area of land by accumulation of soil and the like. In Scotland the Roman term ALLUVIO is used for the same concept. 2 in Scotland, the term used in conveyancing to denote the fortification of a title by subsequent acquisition of ownership. ACCRETION. The increase of land by the washing of the seas or rivers. Hale,De Jure Maris, 14. Vide Alluvion; Avulsion. accretion
Accretion (of a discount)In portfolio accounting, a straight-line accumulation of capital gains on a discount bond in anticipation of receipt of par at maturity.Accretion1. The capital gains a bondholder receives when he/she buys a bond at a discount from par and expects it to mature at par. For example, if one buys a bond at 90% of par, the accretion is 10%. Unless the bond is tax exempt, accretion is taxable each year even though the bondholder does not actually receive any payments until maturity. See also: Imputed value.
2. The addition of value as the result of an outside event. For example, an accretive acquisition occurs if an acquisition increases a company's earnings per share.accretion The accumulation of capital gains on discount bonds with the expectation that the securities will be redeemed at maturity. Excluding municipals, the amount of annual accretion is taxable on an original-issue discount bond even though only a small amount of interest or no interest at all is paid each year. See also imputed interest.accretionThe addition of land through natural causes, such as gradual silting.You will often see accretion used to also describe the addition of land because of receding waters, but this is more properly called dereliction.accretion
