I know these:
[ul]
[li]e.g. = for example[/li]
[li]i.e. = that is[/li]
[li]et al = and others[/li]
[li]etc. = etcetera[/li]
[li]misc. = miscellaneous[/li][/ul]
Is there an abbreviation for the phrase “such as?”
I hope so, because I was almost certain there is one.
There is no difference in meaning, although perhaps in usage:
[ul][li]The SDMB has many forums, such as General Questions and Great Debates.[/li]The SDMB has many forums; for example, General Questions and Great Debates.[/ul]The examples you listed have abbreviations courtesy of their long usage (obviously they have Latin origins). The expression “such as” has not enjoyed the same time-worn popularity and as a consequence has no common abbreviation.
there is a thread floating around in the cyber-darkness of the SDMB wherein members more learned than I posted “all” the abbreviations of this sort. I printed out some of them for my own purposes. If it can’t be found, I’ll post them for you.
The MLA handbook offers MANY accepted abbreviations. (but not one for “such as”)
