This grammar captures the 21st century Spanish use rule but also illustrates how grammar categories are used through multiple graphics and reliable data, even given in percentages. Most of the examples included are authentic, what means that have not been created specifically. The data have been extracted from the Cumbre corpus and from another secondary corpus. "Gramatica practica del espanol actual" consists of 20 units and 4 appendices (numbers, idioms and most common mathematical symbols, time measures and nouns describing people from particular places).
