Source and review context

This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "mass" in a final draft.

If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.

Before you rely on this definition

Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "mass" as the right word for your sentence.

If your draft is formal, technical, persuasive, or sensitive, compare "mass" with a nearby alternative so the final choice matches both meaning and reader expectation.

Compare nearby meanings

  • Use synonyms when you need a softer, stronger, simpler, or more specific word.
  • Use antonyms to check the boundary of the meaning and avoid accidental contrast.
  • Use the example sentence to confirm the word behaves naturally in context.
  • Keep the original wording when a replacement adds complexity without improving precision.

Definition decision workflow

1. Identify the role

Check whether "mass" is acting as adj, name, noun, verb in your sentence. A definition is only useful when the grammar matches the way the word is being used.

2. Test the nearest option

Compare it with "a great number" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.

3. Confirm with context

Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.

Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.

Final meaning check

Before publishing a sentence with "mass", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.

When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

Etymology

Etymology 1

In late Middle English (circa 1400) as masse in the sense of "lump, quantity of matter", from Anglo-Norman masse, in Old French attested from the 11th century, via late Latin massa (“lump, dough”), from Ancient Greek μᾶζα (mâza, “barley-cake, lump (of dough)”). The Greek noun may be derived from the verb μάσσω (mássō, “to knead”), ultimately from a Proto-Indo-European *maǵ- (“to oil, knead”), although this is uncertain. Doublet of masa. The sense of "a large number or quantity" arises circa 1580. The scientific sense is from 1687 (as Latin massa) in the works of Isaac Newton, with the first English use (as mass) occurring in 1704.

Etymology 2

From Middle English messe, masse, from Old English mæsse (“the mass, church festival”) and Old French messe, from Vulgar Latin *messa (“Eucharist, dismissal”), from Late Latin missa, noun use of feminine past participle of classical Latin mittere (“to send”), from ite, missa est (“go, (the assembly) is dismissed”), reanalyzed as "go, [that] is the missa", last words of the Roman Rite of the Catholic Church. Compare Dutch mis (“mass”), German Messe (“mass”), Danish messe (“mass”), Swedish mässa (“mass; expo”), Icelandic messa (“mass”). More at mission.

Etymology 3

From Middle English messe, from Old English mæsse and Old French messe, both from Late Latin missa, from Latin mittō (“to send, dismiss”), compare French messe. In the ancient churches, the public services at which the catechumens were permitted to be present were called missa catechumenorum, ending with the reading of the Gospel. Then they were dismissed with the words: "Ite, missa est", the congregation is dismissed. After that the sacrifice proper began. At its close the same words were said to those who remained. So the word gave the name of Mass to the sacrifice in the Catholic Church. Compare Christmas, Lammas, missal. Doublet of missa.
