In this article we carry out a descriptive study about collective nouns and locative nouns formed by suffixation, which has several objectives: on the one hand, the characterization of suffixes forming each one of these two semantic types of nouns will be presented; on the other hand, we will study what suffixes give rise to both types of nouns and what nouns present both types of meaning. This is what has been called "regular polysemy" in the specialized bibliography.Finally, we will analyze a series of neological collective nouns and locative nouns, extracted from the Bank of neologisms of Cervantes Virtual Center (years 2015 and 2016), in order to determine, among all the suffixes collected from the bibliography, which ones are really productive in the formation of these two types of nouns in Spanish.
