Hola, I'm writing a paper about Preciosa y el aire. I'm having some confusion about when to put "a," "de," or nothing at all between two verbs. Persigue a la niña, tratando __ desvirgarla con fuerza. (He chases the girl, trying to rape her by force). Here we have a gerund followed by an infinitive. Is there a certain rule of what does in between them? Podemos imaginar el viento como un viejo verde y asqueroso que trata ___ forzar a Preciosa. (We can imagine the wind as a dirty, creepy old man who tries to rape Preciosa.) Here we have a conjugated verb followed by an infinitive. Is there a certain rule of what does in between them? Gracias!
