A few prepositions are NOT followed by the prepositional object pronouns listed in this section. Instead, a few prepositions are followed by the SUBJECT pronouns (yo, t, l, ella, usted, ustedes, nosotros, etc).  The special prepositions requiring subject pronouns include:

entre (between)
segn (according to) 
salvo (except)
excepto (except), and 
hasta (until, up to)

Example:    
Entre t y yo, no es verdad.:  Between to you and me, it's not true.
