mass etymology

Etymology

The word "mass" has origins in multiple languages:

  • Latin: "missa," meaning "dismissal" or "sending"
  • Greek (Koine): "ἀπόλυσις" (apolýsis), also meaning "dismissal"

Meaning

The term "mass" has several meanings:

  • Christian Liturgy: A religious service where the Eucharist (Holy Communion) is celebrated, often referred to as the "Holy Mass" or "Eucharistic Mass."
  • Unit of Measurement: A unit of mass in the metric system, equivalent to 1,000 grams (2.2046 pounds).
  • Aggregate or Bulk: A large or heavy collection or quantity of something.
  • Particle Physics: A subatomic particle with no electric charge and large mass, such as a proton or neutron.

Origin

The use of "mass" in the Christian context originated in the early days of the Church. After the Last Supper, Jesus instructed his disciples: "Do this in remembrance of me." (Luke 22:19) This instruction was understood as a command to celebrate a memorial meal, which eventually became known as the Eucharist.

The term "missa" was first used in the 4th century to refer to the conclusion of the Eucharistic liturgy. This was because the bishop or priest would dismiss the congregation with the words, "Ite, missa est," which means "Go, the assembly is dismissed."

Over time, "missa" became the common name for the entire liturgy, including the Eucharist. In the 10th century, the term "mass" was introduced into English, replacing the earlier term "holy communion."

In other contexts, the word "mass" simply means "a large quantity" and is derived from the Latin word "massa," meaning "lump" or "dough." The use of "mass" in particle physics likewise refers to the quantity of matter contained in a particle.
