The English counterpart of Spanish en may be either "on" or "in", while dentro de specifies "within". "Because of" is only one of several possible meanings of por, but por causa de conveys that meaning exclusively. In some cases the compound preposition denotes a literal spatial relationship, while the corresponding simple preposition expresses a figurative version of that relationship: thus, debajo de una mesa ("under a table") vs. bajo un régimen ("under a regime"), or delante de un edificio ("in front of a building") vs. ante un tribunal ("before a court of law").
