ZC Trigram Generator - Version 1.01 The ZC Trigram Generator is a free program that generates new words based on a set of input words. It analyzes the input words and uses them to create random words with similar arrangements of letters. These words are typically pronounceable and completely made-up, but the results generated depend on the set of input words. The ZC Trigram Generator is particularly suited to the generation of proper nouns such as names of people and places.
