Hi , I am asking this because it seems to be opposing views regarding writing a comma after those abbreviations - e.g., i.e. and viz. The Chicago Manual of Style says that a comma needs to be written before and after the abbreviation. A colon or a dash is also possible. It advises that these abbreviations must not be used in formal prose. However, I have seen these abbreviations written in academic articles. This manual of style also says that when you start enumerating a series of things, you should use a comma before the abbreviation as in: "Jane was carrying a lot of stuff in her handbag, e.g.(,) a lipstick, a purse, a notepad, an umbrella, and a chewing gum pack". If a clause is introduced after the first statement, a semicolon needs to be written as in: She saw the last two details; i.e., flowers were waiting and the driver kept mum. (Chicago Manual of Style example, not mine). As I am a new member, I cannot post the link, but if you type that example and "Chicago Manual of Style", you will be able to find it. What do you think regarding the use of a comma after these abbreviations and the use of a semicolon before them? I'd love to hear from native British English speakers. Thank you.
