What Is A Curly Bracket?

As we have mentioned above, a curly bracket/brace or a flower bracket in India looks like this: { }. If you find that you’ve never encountered this form of bracket, don’t worry because you most likely never will as they are very rarely used. However, if you do happen to stumble upon this rare type of bracket, then count yourself lucky because you are about to find out what it means!

Although curly brackets are most commonly used in the field of physics and high-level mathematics, they are also used in writing and music. In writing, curly brackets or braces are used to indicate that certain words and/or sentences should be looked at as a group. Here is an example:

Hello, please pick your pizza toppings {chicken, tomatoes, bacon, sausage, onion, pepper, olives} and then follow me.

In music this type of bracket is referred to as ‘braces’ or ‘accolades’ and they are used to connect two or more lines of music together, to show that they should be played at the same time. In mathematics, curly brackets are used to delimit sets, as well as, indicate the Poisson bracket between two quantities.

When Should You Use Curly Brackets?

Curly brackets/braces were invented in 1967 by Martin Richards. Although this bracket hasn’t been around for as long as the others, it quickly lost its popularity and therefore should be avoided in formal writing, as it is no longer considered appropriate for modern writing.

However, if you plan on using it. Make sure it’s for the right occasion and used correctly, such as for the topics mentioned above. Remember that in writing, curly brackets are used to group statements or ideas together and create a loop. This type of bracket is all about control structure!

Something we did not mention, is that you can also use curly brackets while texting to create a virtual hug, for example: ({) I love curly brackets (})
