Answers to this question assert that there is no difference in meaning between these two words. So they should be merged?

Collins Cobuild English Dictionary:

Nomenclature: The nomenclature of a particular set of things is the system of naming those things [formal]

Terminology: The terminology of a subject is the set of special words and expressions used in connection with it

My opinion is that we do not need both of these tags. I would say to keep "terminology" as it is more widely known/used than "nomenclature".

  • I think there's considerable overlap with single-word-requests, word-choice, vocabulary, words, nomenclature, terminology, and possibly several others. But where will it all end? We can't just tag everything as language. Commented Apr 12, 2011 at 15:52

    I support merging these two tags, and will set up the synonyms myself if no one objects in the next day or two. Commented Apr 12, 2011 at 17:02
