Vietnamese conjunctions are used in daily conversations, especially when you are communicating with Vietnamese people. If you do not know how to use them appropriately, you will most likely have difficulties during your time living in Vietnam.

Jellyfish has compiled all the knowledge about more than 20 common conjunctions in the article below that you can apply today to help you understand and use Vietnamese conjunctions.

I. Types of Vietnamese conjunctions

Conjunctions are words used to connect words with the same function in a clause, or to join clauses of the same type, sometimes to connect main clauses and subordinate clauses. Conjunctions in Vietnamese are divided into two types.

Coordinating Conjunctions: are often used by Vietnamese to connect words or clauses with the same grammatical function in a sentence.

  • In a sentence, coordinating conjunctions are usually placed between words or clauses that are linked together. 


  • Tôi không tin anh ấy, anh ấy đã từng nói dối tôi trong quá khứ (I don’t trust him, for he used to lie to me in the past).
  • Mặt trời mọc những chú chim bắt đầu hót (The sun rises and the birds begin to sing).

Subordinating Conjunctions: are used to connect subordinate clauses and main clauses in a sentence. Subordinating conjunction is placed at the beginning of the subordinating clause, the other being the main clause.

  • Subordinating conjunctions create a relationship between two clauses in a sentence. It can be a cause-effect relationship, a conditional relationship or an opposite relationship, etc.
  • In a sentence, a clause containing a subordinating conjunction can be before or after the main clause.


  • Khi tôi về nhà, em gái tôi đang đọc sách (When I got home, my sister was reading book).
