The # symbol was once called the number sign or pound sign, especially in the US. On Twitter, this symbol started being used to organize topics in 2007.

Difference Between Hashtag, Pound Sign, and Number Sign
In American English, the # symbol is often called a pound sign (mainly for weight, e.g., 5# means 5 pounds). Sometimes, it’s called a number sign, as in #3 for “number 3.” In Twitter or Instagram, it is called a hashtag only if it labels a topic or trend, like #ClimateChange.
How Hashtags Function Across Social Media
On Twitter, Instagram, and other platforms, hashtags connect users to public conversations. Typing a hashtag before a topic word makes posts discoverable by anyone searching for that hashtag. For example, #ExamTips allows students to see all posts on exam advice. Trending hashtags show what is popular or important in different regions or worldwide.

Sample: 500-Word Essay on Why Is The Symbol Called Hashtag In Twitter
The hashtag is a symbol almost every student today recognizes instantly. It is the familiar # sign above the ‘3’ on your keyboard, seen everywhere on Twitter, Instagram, and Facebook. But why is it specifically called a “hashtag” on Twitter, and not simply “number sign” or “pound”?
Let’s start with the origin of the # symbol itself. In the past, in American English, # was known as the number sign—for example, "#5" for "number five"—or as the pound sign, especially when used to indicate weight (pounds). It’s sometimes called “octothorpe” in technical vocabulary. However, the symbol gained brand-new importance in the age of social media, especially when Twitter became popular among young people in the late 2000s.
The modern “hashtag” was born in 2007, when Chris Messina, a technology expert, suggested that Twitter users should prefix their topic words with # to form groups and help others search relevant tweets. For example, #Science would collect all posts about science under one digital roof. Twitter adopted this innovation, and soon users everywhere began using hashtags to join conversations, support causes, and follow trends. The word “hashtag” comes from two words: “hash” (a common British-English word for the # symbol) and “tag” (meaning a label or marker). By joining both, the hashtag became a tool for tagging messages and topics online.
Today, hashtags are used for far more than social chatting. During major events—such as #WorldCup, #Olympics, or #ClimateStrike—hashtags unite people and make every voice count. Students, teachers, celebrities, and leaders use hashtags to share information, run campaigns, and even inspire change. Some hashtags, like #ThrowbackThursday or #ExamTips, are specifically designed for students and go viral every year.
Hashtags work by making messages easy to find. On Twitter, type # and any keyword, with no spaces. Others searching for that hashtag see every public message using it. This also happens on Instagram and Facebook, making social networks more connected and user-friendly.
However, students must be careful about their hashtag use. Using too many hashtags makes posts look spammy. Using unfamiliar or trending hashtags without knowing the meaning may spread misinformation. Always check what a hashtag means, and avoid personal or sensitive data. Good hashtags are short, relevant, and clearly linked to the subject.
To sum up, the # symbol became a “hashtag” on Twitter because it started organizing community conversations online. It builds bridges between people, groups, and even entire movements. Understanding hashtags is essential for students who want to communicate smartly and join global discussions. Whether it’s for a classroom campaign, a trending topic, or simply to find fun stories online, hashtags are now a part of student life, reading, and writing.
