PAST PERFECT SUBJUNCTIVE TENSE


The Past Perfect Subjunctive may be used to indicate an action or state that occurred prior to something in the past (usually expressed by the imperfect or preterit indicative, or by the past subjunctive).  The past perfect subjunctive is formed by using the imperfect subjunctive of the helping verb 'haber' with the past participle:

	hubiera / hubieras / hubiera / hubiramos / hubierais / hubieran   + past participle


Use Past Perfect Subjunctive when discussing situations in the past that are contrary to the fact: 

	Si hubiera ido a la fiesta, habra visto a Isabel.  (If I had gone to the party, I would have seen Isabel.)
	Dudbamos que hubieran llegado.  (We doubted that they had come.)
	Nos gust que todo hubiera salido bien.  (We were glad that all had turned out well.)
