The Imperfect Subjunctive with "Si"
"If I had a million dollars, I'd buy your love! "
In the Spanish world of grammar, those Candian vocal Gods (The Barenaked Ladies) would be lying fools for saying that if they had a million dollars they would buy your love. How can you buy love? You can't. It is very unlikely, impossible, and not true.
So sorry ladies, don't let your hearts break.. The Barenaked Ladies would really not buy anyone's love.
If you remember the conditional tense and the imperfect subjunctive, this tense is extremely easy to form.
You would use the imperfect subjunctive form after si (if), and the conditional in the main part of the sentence.
Let's use the Barenaked Ladies example again ....
If I had a million dollars, I would buy your love !
Si tuviera un millón de dólares, yo comprará su amor !
