when is a verb considered a regular verb in spanish
Spanish verbs The fourteen regular tenses are also subdivided into seven simple tenses and seven compound tenses (also known as the perfect). The seven compound tenses are formed with the auxiliary verb haber followed by the past participle. Verbs can be used in other forms, such as the present progressive, but in grammar treatises they are not usually considered a special tense but rather periphrastic verbal constructions.
