This book chapter presents a descriptive-analytical sample from the pluridimensional linguistic atlas of the Portuguese spoken in the Médio Tietê region, São Paulo State, Brazil. Four semantic-lexical variables were investigated in the form of questions posed to 80 informants as follows: What is a heavy, short-lasting rainfall called? What is the name given to the star that appears before (and shines brighter than) the others in the sky close to the horizon by late afternoon and is the last to disappear? What is the name of the root that resembles regular cassava but is poisonous and, because of that, needs a specific cooking method by which it becomes safe for consumption? What do you call someone who has bow legs? The most frequent variants collected in the form of answers are , , , and respectively.
They were mapped with others and analyzed within the framework of pluridimensional dialectology.
