      Partnering, along with its less irritating cousin "partnership", crops up all over the place, being equally useful to the lazy jargoneer and the lazy policy-maker. It has been said that there is no noun which cannot be verbed; in the same way, there is now nothing, concrete or abstract, which cannot be partnered.

Usage notesEdit

  • People who have common grandparents but different parents are first cousins. People who have common great-grandparents but no common grandparents and different parents are second cousins, and so on.
  • In general, one's nth cousin is anyone other than oneself, one's siblings or nearer cousins found by going back n+1 generations and then forward n+1 generations. One of one's first cousin's parents is one's parents' siblings. One of one's second cousin's grandparents is one of one's grandparents' siblings.
  • The child of one's first cousin or the first cousin of one's parent is one's first cousin once removed; the grandchild of one's first cousin or the first cousin of one's grandparent is one's first cousin twice removed, and so on. For example, if Phil and Marie are first cousins, and Marie has a son Andre, then Phil and Andre are first cousins once removed.
  • In the southern US, the relation is considered the number of links between two people of common ancestry to the common aunt or uncle.
