This is a one page reference sheet that I created one day after I was trying to clear up the difference between the future and future perfect for a student after school. I wrote the various perfect tenses on the board and then left it there simply because I forgot to erase it. The next day students asked me to put that into a notes page for them and so, here it is! It is an explanation of the majority of the perfect tenses:
Past perfect (pluperfect)
Present perfect of the subjunctive
It includes the conjugations of each tense, examples in context, then the translation in English.
