What is i.e.?

i.e. stands for the Latin phrase "id est," which translates to "that is" or "in other words." It is used to clarify a previous statement by providing a more specific explanation or rephrasing it for better understanding. Essentially, it introduces an elaboration or definition of the preceding point.

Here's a breakdown:

• Purpose: Clarification, restatement, or providing a more specific example.
• Usage: Followed by a comma and the clarifying information.
• Example: "I enjoy outdoor activities, i.e., hiking and camping."
• Distinction from e.g.: i.e. provides a more precise restatement, while e.g. provides examples. For the e.g. abbreviation, refer to the relevant information.
• Formality: Generally considered acceptable in formal writing.
