If given a positive numerical prefix, fetch that many articles back into
the ancestry. If given a negative numerical prefix, fetch just that
ancestor. So if you say @kbd{3 ^}, Gnus will fetch the parent, the
-grandparent and the grandgrandparent of the current article. If you say
-@kbd{-3 ^}, Gnus will only fetch the grandgrandparent of the current
+grandparent and the great-grandparent of the current article. If you say
+@kbd{-3 ^}, Gnus will only fetch the great-grandparent of the current
article.
