Abstract: The aim of this research is to explore the question called “hypothesis of the inverse relationship between neologicity and dictionarizability” based on the perception surveys (Neómetro project, Universitat Pompeu Fabra of Barcelona) where some objective and quantifiable parameters should lead to the complex concept of neologicity. The results allow us to note the existence of positive or negative neologicity models and also to see what relationship these models keep with dictionarizability.
