Help:Piped link
A piped link is a link within the project which is labeled differently from the name of the page it links to. This allows linking a word or phrase within the text of a page rather than using "see also", even if the wording does not exactly correspond with the name of the other page. With a suitable browser and depending on the preferences set, one can still see what page is linked to: when you point at the link, the name shows up in a hover box and is also shown in the status bar.
For instance:
[[New York Mets|mets home page]]
will show: mets home page
The term piped refers to the use of the pipe character "|" used to separate the good description from the actual link.
