neology

Neology or Neologism, is an expression most frequently associated with the coining of new words, from the Greek root (Neo-: new, and Logos-: the word). This practice may be compared with other less mentally intensive, although sometimes computationally intensive forms of wordplay such as anagrams and acrostics, as well as fully developed theories or practices of language, such as aphorisms, poetics, and literary essays.
