(v.) To create, coin, or utilize a previously undefined word; to combine portions of one or more words, prefixes, and/or suffixes to produce a new word.
The pop-culture term sniglet refers to the new word itself, while the act of devising new sniglets is vocabularization. Although similar, it should be noted that acronyms and shorthand abbreviations remain distinct practices outside the scope of vocabularization.
