[Middle English, from Old French, from Latin metallum, from Greek metallon, mine, ore, metal.]
Word History: In modern English, metal and mettle are pronounced the same, and they are in fact all related. Middle English borrowed metal from Old French in the 14th century; Old French metal, metail, came from Latin metallum, from Greek metallon, "mine, quarry, ore, metal." By the 16th century, metal had also come to mean "the stuff one is made of, one's character," but there was no difference in spelling between the literal and figurative senses until about 1700, when the spelling mettle, originally just a variant of metal, was fixed for the sense "fortitude." The history of English has numerous examples of pairs of words, like metal and mettle, that are (historically speaking) spelling variants of the same word; two other such pairs are trump/triumph and through/thorough.

mass

In physics, the property of matter that measures its resistance to acceleration. Roughly, the mass of an object is a measure of the number of atoms in it. The basic unit of measurement for mass is the kilogram. (See Newton's laws of motion; compare weight.)


meter

The basic unit of length in the metric system; it was originally planned so that the circumference of the Earth would be measured at about forty million meters. A meter is 39.37 inches. Today, the meter is defined to be the distance light travels in 1 / 299,792,458 seconds.

Word Origin & History

Mach 
measure of speed relative to the speed of sound (technically Mach number), 1937, named in honor of Austrian physicist Ernst Mach (1838-1916).

mass  (2)
"Eucharistic service," O.E. mæsse, from V.L. *messa "eucharistic service," lit. "dismissal," from L.L. missa "dismissal," fem. pp. of mittere "to let go, send," from concluding words of the service, Ite, missa est, "Go, (the prayer) has been sent," or "Go, it is the dismissal."

meta- 
prefix meaning 1. "after, behind," 2. "changed, altered," 3. "higher, beyond," from Gk. meta (prep.) "in the midst of, among, with, after," from PIE *me- "in the middle" (cf. Goth. miþ, O.E. mið "with, together with, among," see mid). Notion of "changing places with" probably led to senses "change of place, order, or nature," which was the principal meaning of the Gk. word when used as a prefix. Third sense, "higher, beyond," is due to misinterpretation of metaphysics (q.v.) as "transcending physical science."

meter  (3)
"device for measuring," abstracted 1832 from gas-meter, etc., from Fr. -mètre, used in combinations, from L. metrum "measure" or cognate Gk. metron "measure" (see meter (2)). Meter maid first recorded 1957.

Abbreviation of mass, meter
Mach   (mäk, mäKH)  Pronunciation Key 
Austrian physicist and philosopher who experimented with supersonic projectiles and the flow of gases, obtaining early photographs of shock waves and gas jets. His work laid an important foundation for later developments in the science of projectiles and aeronautical design, and the Mach number and Mach bands were named for him.
mass   (mās)  Pronunciation Key 
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.
meter   (mē'tər)  Pronunciation Key 
The basic unit of length in the metric system, equal to 39.37 inches. See Table at measurement.
