At times we found that we have important information which we want to include in a sentence but find it difficult to create a spot for all of it. It can become tricky to fit everything into a sentence. Brackets (parenthesis) are punctuation marks used in a sentence to include information that is not crucial to the main point. Supplementary information used within brackets, will not change the meaning of the sentence was it removed, the reader will benefit from knowing this additional information. This type of information is normally used in formal and informal writing for two completely different purposes. Be careful not to overuse parenthesis, it can lead to a cluttered and confusing text.

Brackets

Not all kinds of brackets are acceptable for use within all disciplines of writing.
There are four main types of brackets namely:

Angle brackets <...> are naturally used to enclose and illustrate highlighted information.

Brackets used in a short story or business plan can be an effective way to include additional information in a sentence. If used overly, the clarity of your writing will suffer.

Brackets [{(<>)}] are used to enclose a parenthesis; e.g., something put into a sentence by the way and not really a part of it; e.g., "Martha (you know her, don't you?) has promised to play for us." "Saul (afterwards called Paul) persecuted the Christians."
Sometimes dashes are used instead of brackets: e.g., "Saul---afterwards called Paul---persecuted the Christians."
Note that brackets do not mean." delete."
