Commas ',' are used in sentences and writing, yet few understand their specific functions and purposes. In this article, we'll explore commas and how to use them most effectively.

1. What is a Comma?
Commas and semicolons are used to pause or interrupt within a sentence. However, each punctuation mark serves a different purpose, leading to confusion among many writers.

Commas (symbol: ,) are punctuation marks used to interrupt a sentence or introduce another idea within a sentence, or to divide elements in a list. Additionally, commas are used to separate clauses within a sentence.
Example of comma interrupting a sentence/ introducing another idea within a sentence:
Nắng thu giờ đây chỉ là những tia nắng nhẹ, mang theo gió heo may khô khốc của tiết trời |
In this example, the comma is used to interrupt the sentence, making it easier for readers to understand and preventing the sentence from becoming convoluted.
Example of comma dividing elements in a list:
Đất trời có bốn mùa xuân, hạ, thu, đông, mỗi mùa lại có một vẻ đẹp riêng của nó.. |
In this example, commas are used to divide elements in a list, specifically listing the seasons of the year (spring, summer, fall, winter).
Example of comma dividing elements in a sentence:
Mỗi khi mùa hè về, đám nhỏ lại ra dòng sông vui đùa tắm mát. |
In this example, commas are used to separate the Adverbial/Prepositional phrase, Subject - Verb.
