A Study of the Structure of Persian and Spanish Verbs with Emphasis on the Book “El libro de los abrazos”

The verb is one of the important pillars of grammar, the structure of which is disputed by grammarians. Hence, research to remove ambiguity has become one of the most important necessities of grammar. In this article, with a comparative study of verb structure in both Persian and Spanish, with regard to the verbs of the book "El libro de los abrazos" and its Persian translation, first the cause of disagreement about verb structure, then the way out of them provide an appropriate comparative classification of verb properties in both languages. During the research, it was found that the main reason for the disagreement about the structure of the verb is related to the type of division of language morphemes by the experts and the position of the preposition in it. After reviewing, we put the preposition below the lexical morpheme and considered the result of noun / adjective / adverb / verb / preposition+ verb as "compound verb" and the result of noun / adjective / adverb + derivative verbs as "derivative verb". In addition to providing a comparative division of verb structure in two languages and removing ambiguities about derivative and compound verbs, it became clear what the reason for the frequency of compound verbs in Persian compared to Spanish was.
