What is the proper name for a pair of vertices connected by an edge?

NOTE: Lots of googling didn't yield an answer.

DISCLAIMER: I am no math expert.

    I thought you were looking for the term which fits the definition you provided. If you want a more concise term then you can use it in the following manner "Vertices A & B are adjacent".2011-05-20

    @jldupont: are you looking for a _term_ or a _definition_? Besides "adjacent vertices" I can only think of "neighboring vertices" as far as terms. These are already relatively short terms. I suppose if you really wanted to, you could define a shorter term yourself, but I don't really see the point of this.2011-05-20
