Learn English – How to pronounce/say the abbreviation ‘i.e.’

abbreviationspronunciation

I know that 'i.e.' is an abbreviation of 'that is'. But, my question is about pronouncing it perhaps,

  1. in normal speech,
  2. reading from a piece of text containing the abbreviation, etc.

In the US, most people (I have interacted with) pronounce 'i.e.' by uttering the two letters 'I' and 'E'. So, it would sound like 'eye ee'.

However, I have heard very few Americans say 'that is' instead of 'eye ee'. I have observed this when I saw them read a piece of text like a news article. It's like they replaced 'i.e.' with 'that is' in the text and then, read it.

How common is the latter pronunciation in the US? How is 'i.e.' said in the rest of the English-speaking world?

Best Answer

In normal speech, I would say "that is." I would not say "eye ee" for a couple of reasons.

  • The audience may not actually know what "eye ee" means.
  • It could be ambiguous because another term IE could mean something other than "that is". Consider a speech about web browsers. The audience would not know what you are referring to when you say "eye ee". Is that i.e. or is that Internet Explorer? The audience can probably come to the conclusion of which one it is, but for clarity, you should say "that is".
  • Public speakers do not usually say i.e., so you should follow that convention.

While reading i.e. from text, I still say "that is." It is the same with e.g., I would say "for example." However, it is not incorrect to say "eye ee" since you, yourself know what the context is, it is fine.

To summarize, it is very common to say "that is". If you are reading aloud to listeners who are unable to see the text, I would recommend saying "that is" to avoid any ambiguity. If they can see the text and clearly know that you are conveying the abbreviation i.e, you can say "eye ee". If you prefer, you can say the full latin: id est
