PEhE (http://www.lojban.org/en/publications/reference_grammar/chapter14.html)

Precedes a logical or non-logical connective that joins two termsets. Termsets
(see CEhE) are used to associate several terms for logical connectives, for equal
quantifier scope, or for special constructs in tenses.

John [,] James are-friends-of. I am a friend of you, and John is a friend of
James.
