It contains a classification and frequency of occurrence of the irregularities of Spanish verbs, which have led to 159 conjugation models. There are 460 simple conjugations corresponding to the conjugation models and to all the verbs that admit more than one conjugation. The conjugation includes the voseo forms, normally used in Río de la Plata, and the forms of respect usted and ustedes, the latter also used in the Canary Islands and other areas on a daily and informal basis. All the conjugations are accompanied by their morphological information, their defectivity, usage notes, other verbs that are conjugated the same and, for the verbs with more than one conjugation, their meaning.
