Common Mistake: Using "parenthesis" instead of "parentheses"

One common mistake that many people make is using the word "parenthesis" instead of "parentheses." This error often stems from confusion over the correct plural form of the word "parenthesis."

Example: The sentence "Please enclose your name and address in parenthesis" is incorrect.

Correction: The correct sentence should be "Please enclose your name and address in parentheses."

It's important to understand the distinction between these two words in order to communicate effectively in written English.

The Singular Form: Parenthesis

The word "parenthesis" refers to a single bracket or curved line used in writing to separate or enclose additional information within a sentence.

The Plural Form: Parentheses

On the other hand, "parentheses" is the plural form of the word and is used when referring to multiple brackets or curved lines.

Example: In the sentence "I need to buy some new parentheses for my mathematical equations," the word "parentheses" is used correctly to indicate more than one bracket.
