3. Definition Section

3.1. What is “Moral”?

Etymology and Historical Context: The word moral comes from the Latin moralis, meaning “relating to manners or morals,” which itself comes from mos, moris (“custom, habit”). Usage in English dates back to the late Middle Ages, mainly in the context of distinguishing right from wrong.

Part of Speech: “Moral” can function both as a noun and an adjective:

  • Noun: Refers to a lesson from a story or guiding principle of right and wrong.
  • Adjective: Describes actions, people, or ideas related to right and wrong (e.g., “a moral decision”).

Basic Meanings:

  • As a noun: “A lesson about right and wrong” (e.g., “The moral of the story is to be honest.”)
  • As a noun (plural: “morals”): “Principles or standards of behavior” (e.g., “She has strong morals.”)
  • As an adjective: “Concerning the distinction between right and wrong” (e.g., “He faced a moral dilemma.”)

3.2. Plural of “Moral”: Definition

The plural of moral is morals. While the singular refers to a single lesson or principle, the plural often refers to a set of principles or standards.

  • Singular: “The moral of the story was clear.”
  • Plural: “He questioned his morals.”

Difference in Meaning:

  • Singular “moral”: Usually means a specific lesson or principle, often associated with stories or parables.

Note: Always use “morals” (plural) when referring to a set of ethical principles.

3.3. Grammatical Classification

Noun Classification: “Moral” is a countable noun when referring to a lesson (You can have one or many morals of stories). “Morals” is a plural countable noun when referring to ethical standards, but in this use, it often behaves like a collective or abstract noun.

  • Countable: “There are several morals in these fables.”
