E.g. vs. I.e.
E.g. and i.e. serve different functions: one introduces examples and the other identifies or restates what is meant. The guide keeps that semantic choice separate from punctuation-specific guidance.
Use e.g. for examples and i.e. for a restatement or clarification: e.g. means “for example,” while i.e. means “that is.”
