Editing Italian grammar (section)

==Disputed points in Italian grammar==
Among sometimes proscribed Italian forms are:
* The usage of an indicative form where a subjunctive one is traditional; for instance: ''credo che Giorgio ieri fosse a casa'' ("I believe that yesterday George was at home") is considered proper, while ''credo che Giorgio ieri era a casa'' may not be; ''se Maria fosse stata a casa, le avrei telefonato'' ("if Mary had been at home, I would have telephoned her") is preferred, ''se Maria era a casa le telefonavo'' is often proscribed, despite being found in classic Italian writers.
* The use of the object forms (''lui'', ''lei'', ''loro'' and ''Lei'') of third person pronouns instead of the subject forms (''egli'', ''ella'', ''essi'', and ''Ella''), which are employed in formal language.
* ''Ma però'', despite being widespread in spoken language, is proscribed in formal usage because it is redundant (''ma'' and ''però'' are synonyms).
