Relative Clauses in Vietnamese

Overview

Vietnamese relative clauses modify nouns using the optional relativizer "mà" (which/that/who). Unlike English, where relative clauses follow the noun with "who," "which," or "that," Vietnamese often omits the relativizer entirely, relying on word order and context. The modified noun comes first, followed by the modifying clause.

At the CEFR B1 level, relative clauses enable complex descriptions and specifications. "Người đến" (the person who came), "sách tôi đọc" (the book I read), and "nhà hàng mà chúng ta đi" (the restaurant that we went to) all use this structure to embed information about nouns.

The optional nature of "mà" means Vietnamese relative clauses can be very compact. "Người tôi gặp" (person I met = the person I met) is a complete relative clause construction with no visible marker.

How It Works

Pattern	Example	Meaning
Noun + (mà) + Subject + Verb	sách (mà) tôi đọc	the book (that) I read
Noun + Verb (subject relative)	người đến	the person who came
Noun + (mà) + clause	nơi (mà) tôi sống	the place where I live

Mà is optional but adds clarity in complex sentences:

With mà	Without mà	Meaning
Người mà tôi gặp	Người tôi gặp	the person (whom) I met
Sách mà tôi đọc	Sách tôi đọc	the book (that) I read

Examples in Context

Vietnamese	English	Note
Người (mà) sống ở đây.	The person who lives here.	subject relative
Sách (mà) tôi đọc.	The book that I read.	object relative
Nhà hàng (mà) chúng ta đi.	The restaurant where we went.	place relative
Lý do (mà) tôi đến.	The reason why I came.	reason relative
Bạn (mà) tôi nói	The friend I mentioned	omitted mà
Cái áo mà tôi mua hôm qua.	The shirt that I bought yesterday.	with mà for clarity
Thời gian mà tôi ở Việt Nam.	The time when I was in Vietnam.	temporal relative
Người giúp tôi rất tốt.	The person who helped me is very kind.	no mà needed
Đây là món mà tôi thích nhất.	This is the dish I like most.	with mà
Nơi tôi sinh ra.	The place where I was born.	no mà

Common Mistakes

Adding Extra Pronouns in the Relative Clause

• Wrong: Người mà tôi gặp anh ấy (the person that I met him)
• Right: Người mà tôi gặp (the person that I met)
• Why: The relativized noun is already understood; adding a pronoun creates redundancy.

Using Mà When It Creates Ambiguity

• Wrong: Using "mà" as a relative marker when it could be interpreted as "but"
• Right: Omit "mà" or restructure when context is ambiguous
• Why: "Mà" has multiple meanings (relative marker, but, yet). Context must disambiguate.

Usage Notes

In spoken Vietnamese, "mà" is frequently omitted in simple relative clauses. It is retained more often in writing and in complex sentences where clarity is needed. There is no grammatical error in either including or omitting it.

Vietnamese does not change the form of "mà" for subject vs object relatives (unlike English who/whom/which). The single word "mà" covers all relative clause types.

Practice Tips

• Practice building relative clauses by combining two sentences: "Tôi đọc sách" + "Sách hay" = "Sách (mà) tôi đọc hay" (The book I read is good).
• Start without "mà" to build compact natural-sounding relatives, then add "mà" when you notice ambiguity.
