Is a good day to learn english, you are welcome to practice with me. My name is Sebastián Orduz and this is My podcast about have to vs hafta. I have heard frequently the word hafta, but what is hafta? - hafta is the informal contraction that joins the word have to the word to.

This contraction is an example of linking sounds, where you join the final sound with the begining sound of the next word in a just sound.

Why native speakers say hafta opposite to have To? Because is more easy join two sounds in one.
