I am looking for two words that would describe:
- merge from two branches or forks;
- merge from three branches or forks.
PS: am I "allowed" to continue the respective series by applying different numbers in Latin?
I frequently use the word "(Re)anneal" to describe that phenomenon – (re)connections in computer networks are a constant. However, that's the term I used a lot when studying biochemistry, where it refers to the process in which two single strands of DNA recombine into their bonded helical form.
More generally, there's "consilience", which roughly means "a springing together" – like disparate facts suddenly lining up to tell a story, or maybe an interdisciplinary tapestry of the sort used by the Game's players in Hermann Hesse's timeless book Magister Ludi ("The Glass Bead Game").
