Definition

1. Adverb:

   • That is to say; in other words: Used to introduce a clarification, explanation, or rephrasing of what has just been stated. It is an abbreviation for the Latin phrase "id est."

2. Noun:

   • A commercial browser: A proprietary web browser developed by Microsoft, Internet Explorer, commonly abbreviated as IE.

Usage

• Adverb: The abbreviation "i.e." is used in writing to specify or explain something more precisely. It is typically followed by a comma and introduces a restatement.
• Noun: The term "IE" (often capitalized) is used as a proper noun to refer specifically to the Internet Explorer software.

Examples

• Adverb:
  • The event is for the founding members, i.e., those who joined in the first year.
  • Please bring all necessary items, i.e., your passport, ticket, and confirmation number.
• Noun:
  • Many older websites were designed specifically for IE.
  • The company will no longer support IE after this year.

Advanced Usage

• Punctuation with "i.e.": In modern English, it is standard to follow "i.e." with a comma when it introduces an explanatory phrase or clause.
  • The meeting is postponed until next week, i.e., Monday the 14th.
• Stylistic Note: In formal writing, "i.e." is often set off by parentheses or dashes to integrate the explanation smoothly into a sentence.
  • The herbivore (i.e., the plant-eating animal) was grazing quietly.

Variants and Related Words

• e.g.: An abbreviation for the Latin "exempli gratia," meaning "for example." It is often confused with "i.e." but serves a different function (introducing examples rather than a clarification).
  • Bring writing utensils, e.g., pens and pencils.
• viz.: An abbreviation for the Latin "videlicet," meaning "namely" or "that is to say," used similarly to "i.e." but is more formal and less common.
• Internet Explorer: The full name for the browser abbreviated as IE.

Synonyms

• Adverb:
  • That is
  • In other words
  • Namely
• Noun:
  • Browser (general term)

Related Phrases

• i.e., vs. e.g.: A common point of confusion. Remember: "i.e." clarifies ("in other words"), while "e.g." gives examples ("for example").
  • We need tools, i.e., items that help us fix things. (Clarification: tools are defined as fixing items.)
  • We need tools, e.g., a hammer and screwdriver. (Examples: a hammer and screwdriver are types of tools.)

Notes

• The adverbial form "i.e." is traditionally written with periods, though the unpunctuated form "ie" is sometimes seen in informal contexts.
• When used as a noun for the browser, "IE" is typically written in uppercase without periods.
