However, if you want to add some variety to your vocabulary, there are several other words that you can use to describe the same concept. Some popular synonyms for "fictionary" include "neologism" (a newly-coined word or phrase), "nonce word" (a word invented for a particular occasion), "portmanteau" (a word created by blending two or more existing words), and "coinage" (the act of inventing a new word or phrase). These synonyms are great options to use when you want to sound more sophisticated or expand your linguistic knowledge.
