Hello! The simple conditional is used to express a wish or ask for/require sth in an attenuated way : ¿Podrías cantar esta canción? Would you please/could you sing this song? ¿Podrías ayudarme? Would you please/could you help me? (It's the same as in English: Can you help me? => Could you help me?) This form is also used to give advice: Creo que podrías/deberías decírselo a tu amigo. I think you should tell it to your friend. Yo, en tu lugar, no podría hacerlo. If I were you, I couldn't / wouldn't be able to do it. It's also used in sentences like: Si tuvieras mucho dinero, podrías comprar esta casa. If you had a lot of money, you could/ would be able to buy this house. Finally, if you use reported speech, the future tense of the original sentence will be changed to a conditional: Te digo que podré (I tell you that I will be able to...) => Le dijo que podría... (He told him that he would be able to/could...) The use of "might" in English indicates a possible occurence in the future. In Spanish, to convey this idea, you would rather use "Es possible que..." / "Puede ser que" or use "tal vez", "a lo mejor", "posiblemente", "quizás"...
