RT Journal Article T1 Written type and token frequency measures of fifty Spanish derivational morphemes A1 Lázaro López-Villaseñor, Miguel A1 Acha, Joana A1 Illera, Víctor A1 Sainz Sánchez, Francisco Javier AB Several databases of written language exist in Spanish that manage important information on the lexical and sublexical characteristics of words. However, there is no database with information on the productivity and frequency of use of derivational suffixes: sublexical units with an essential role in the formation of orthographic representations and lexical access. This work examines these two measures, known as type and token frequencies, for a series of 50 derivational suffixes and their corresponding orthographic endings. Derivational suffixes are differentiated from orthographic endings by eliminating pseudoaffixed words from the list of orthographic endings (cerveza [beer] is a simpleword despite its ending in -eza). We provide separate data for child and adult populations, using two databases commonly accessed by psycholinguists conducting research in Spanish. We describe the filtering process used to obtain descriptive data that will provide information for future research on token and type frequencies of morphemes. This database is an important development for researchers focusing on the role of morphology in lexical acquisition and access.
