What is id est?

Id est, commonly abbreviated as i.e., is a Latin phrase meaning "that is." It is used in written language to provide clarification or explanation for a statement or expression that has just been made. Id est can be used interchangeably with "in other words" or "that means."

For example, in the sentence "I like to eat fruits, i.e., apples, bananas, and oranges," the phrase "i.e." is used to specify the types of fruits the speaker likes.

Id est is often written in lowercase letters with periods after each letter, but it can also be capitalized and written as i.e. with or without periods. It is commonly used in academic writing, legal documents, and technical manuals.
