Abbreviations

Abbreviations are often used in chat and other places in Guild Wars 2. The following article aims to document the abbreviations seen most usually. Note that none of these abbreviations are case sensitive in practice, and their appearance in-game will vary accordingly.

The page does not aim to be all-encompassing, but rather to cover:

• Terms that are likely to be encountered (i.e. if you haven't seen it used commonly in chat, it's probably not well known enough and thus not likely encountered).
• Terms that are relevant to gameplay (e.g. no need to explain meanings of widely known social abbreviations such as "lol")

Other abbreviations and terms may be found at the following links:

• Abbreviations specific to World versus World may be found here.
• Some other non-abbreviation terms can be found at Common terms or in the Glossary category.

When adding new abbreviations:

• If the abbreviated and non-abbreviated terms are both common, list both.
• If the term varies in capitalization, just list the most common abbreviation. (e.g. AB instead of Ab.)

You can reach this page from in-game at any time by typing /wiki Lingo into the chat box.
