Question 1

What is the difference between i.e. and e.g.?

Accepted Answer

i.e. means 'that is': what follows is the same thing said more precisely, and it's complete. e.g. means 'for example': what follows is a sample, and there are others. 'Bring a hot drink, i.e. tea' means tea is the only option; 'bring a hot drink, e.g. tea' means tea is one of several.

Question 2

How do I know if I mean i.e. rather than e.g.?

Accepted Answer
