Questions & Answers about Người ác lừa họ.
Because in Vietnamese, adjectives usually come after the noun they describe.
So:
- người = person
- ác = evil, cruel, wicked
That makes người ác literally person evil. This is normal Vietnamese word order, even though English would say evil person.
By itself, it can be singular, plural, or generic, depending on context.
Vietnamese bare nouns are more flexible than English. For example:
- một người ác = one evil person
- những người ác = evil people
Without một or những, the sentence leaves that open. In real use, context tells you whether it means an evil person, the evil person, or evil people in general.
Vietnamese does not have articles in the same way English does.
That means a noun phrase like người ác can often work without anything equivalent to a/an/the. If a speaker wants to make one explicit, they can say một người ác. If they want plural, they can say những người ác.
So the lack of an article here is completely normal.
