Tone: Serious, Reflective
Frequency: ⭐⭐⭐⭐⭐ (Very Common)
CEFR Level: B1
Example Sentence 1: “She is a highly moral person who always tells the truth.”
Example Sentence 2: “The moral of the story is to always be kind.”
Usage Tip: “Moral” is the most direct synonym and can be used in almost any context. It’s a safe, natural choice. Remember, “morale” (with an ‘e’) means the spirit of a group, and “moral” is about right and wrong.
Common Confusion: Moral vs Ethical – “Moral” is more personal, often based on religious or personal beliefs. “Ethical” is more professional, often based on rules of a profession or society.

Example Sentence 1: “The queen was known as a virtuous and wise ruler.”
Example Sentence 2: “He led a virtuous life, always helping those in need.”
Usage Tip: “Virtuous” is a bit old-fashioned. It’s perfect for stories or historical writing. In modern conversation, “moral” is more natural. Don’t use “virtuous” to describe yourself—it can sound boastful!
