The easiest way to increase your vocabulary is to MAKE UP WORDS! Like the amusing "interocitor" from an old s-f movie. Here is a new way to make up words: combine prefixes and suffixes with no substantive element in between, forcing them to take on substantive roles themselves. Here are some new words of that style. The big bonus for logologists is that these may now be treated as legit words since they have appeared in print as bold entries in a linguistics journal!
