In Vietnamese grammar, Personal Pronouns play a significant role in conveying a message clearly. Similar to other languages, Vietnamese uses different personal pronouns for the subjective, objective, and possessive case, often signifying respect and social distance. Unlike in English, where pronouns do not denote social relationship and hierarchy, Vietnamese personal pronouns are rich in this aspect. Thus, understanding and using the appropriate personal pronouns is crucial to the fluency and appropriateness in Vietnamese communication.
