Questions & Answers about Boni mores plus valent quam divitiae.
Because mores is plural, and the adjective has to agree with it.
- bonus = good (masculine singular nominative)
- boni = good (masculine plural nominative)
Since mores is masculine plural, Latin uses boni mores = good morals / good character / good conduct.
In Latin, mos means something like custom, habit, or moral character. Its plural, mores, is very commonly used to mean:
- morals
- character
- conduct
- customs
So boni mores is a very natural Latin expression. It does not just mean several separate customs; it can also mean a person's good moral character or good behavior more generally.
Both are nominative plural.
- boni mores = nominative plural masculine
- divitiae = nominative plural feminine
