MediaWiki:Word-separator/qqq

Optional This is a string which is (usually) put between words of the language. It is used, e.g. when messages are concatenated (appended to each other). Note that you must express a space as html entity &amp;#32; because the editing and updating process strips leading and trailing spaces from messages.

Most languages use a space, but some Asian languages, such as Thai and Chinese, do not.
