Subject: 26.3; Doc string of `read-regexp-suggestions'

Return a list of standard suggestions for `read-regexp'.
  By default, the list includes the tag at point, the last isearch regexp,
  the last isearch string, and the last replacement regexp.  `read-regexp'
  appends the list returned by this function to the end of values available
  via M-n.

What's "the tag at point"?  What does "tag" mean here?  I have no idea.
