Origin of Mass
- a large coherent body of matter without a definite shape
- a collection of the component parts of something
- a large amount or number, such as a great body of people
- the main part or majoritythe mass of the people voted against the government's policy

- the size of a body; bulk
- physics a physical quantity expressing the amount of matter in a body. It is a measure of a body's resistance to changes in velocity (inertial mass) and also of the force experienced in a gravitational field (gravitational mass): according to the theory of relativity, inertial and gravitational masses are equalSee also inertial mass, gravitational mass

Word Origin for mass
Word Origin for Mass
"to gather in a mass" (intransitive), 1560s, from mass (n.1) or from French masser. Transitive sense by c.1600. Related: Massed; massing.
"lump, quantity, size," late 14c., from Old French masse "lump, heap, pile; crowd, large amount; ingot, bar" (11c.), and directly from Latin massa "kneaded dough, lump, that which adheres together like dough," probably from Greek maza "barley cake, lump, mass, ball," related to massein "to knead," from PIE root *mag- "to knead" (cf. Lithuanian minkyti "to knead," see macerate). Sense extended in English 1580s to "a large quantity, amount, or number." Strict sense in physics is from 1704.
As an adjective from 1733, first attested in mass meeting in American English. mass culture is from 1916 in sociology (earlier in biology); mass hysteria is from 1914; mass media is from 1923; mass movement is from 1897; mass production is from 1920; mass grave is from 1918; mass murder from 1880.
"Eucharistic service," Old English mæsse, from Vulgar Latin *messa "eucharistic service," literally "dismissal," from Late Latin missa "dismissal," fem. past participle of mittere "to let go, send" (see mission); probably so called from the concluding words of the service, Ite, missa est, "Go, (the prayer) has been sent," or "Go, it is the dismissal."
- A unified body of matter with no specific shape.
- A grouping of individual parts or elements that compose a unified body of unspecified size or quantity.
- The physical volume or bulk of a solid body.
- The measure of the quantity of matter that a body or an object contains. The mass of the body is not dependent on gravity and therefore is different from but proportional to its weight.
- A thick, pasty pharmacological mixture containing drugs from which pills are formed.
- One of the seven fundamental SI units, the kilogram.
- A measure of the amount of matter contained in or constituting a physical body. In classical mechanics, the mass of an object is related to the force required to accelerate it and hence is related to its inertia, and is essential to Newton's laws of motion. Objects that have mass interact with each other through the force of gravity. In Special Relativity, the observed mass of an object is dependent on its velocity with respect to the observer, with higher velocity entailing higher observed mass. Mass is measured in many different units; in most scientific applications, the SI unit of kilogram is used. See Note at weight. See also rest energy General Relativity.
