There are syntactic, semantic, and pragmatic motivations for choosing the passive voice instead of the active.[8] Some languages, such as English and Spanish, use a periphrastic passive voice; that is, it is not a single word form, but rather a construction making use of other word forms. Specifically, it is made up of a form of the auxiliary verb to be and a past participle of the main verb which carries the lexical content of the predicate. In other languages, such as Latin, the passive voice for some tenses is simply marked on the verb by inflection: librum legit "He reads the book"; liber legitur "The book is read".
