To express ‘I wish I could’ in Spanish, you would say ‘Ojalá pudiera’. This phrase is commonly used when you want to convey a sense of longing or desire for something that is not possible. In this context, ‘Ojalá’ translates to ‘I wish’ and ‘pudiera’ is the imperfect subjunctive form of the verb ‘poder’, meaning ‘to be able to’.
Using ‘Ojalá’ adds a layer of hope and emotion to the sentence, making it clear that you are wishing for a different reality or outcome. For example, if you wanted to say, ‘I wish I could go to the concert’, you would say, ‘Ojalá pudiera ir al concierto’.
