Poder = to be able to

Were you wondering how you can tell someone in Spanish that you can do something that they asked you to do? Poder is the verb that you should be using. Poder has an o to ue conjugation, which means that the o becomes ue when referring to the conjugations in yo, tú, él / ella / ud, and ellos(as) / ustedes.

If you want to tell someone that you can either do or make something you would say, "Yo puedo hacerlo".
