Pie

I had never heard the words "Savory pie" until today.  

Because I have little English vocabulary, I am trying to improve my skills, which means studying a little. Today, I used the word "pie" to indicate a dessert, but a friend did not understand which sweet or salty pie it was. I knew meat pie but I did not recognize meat pie as "pie" because it was not sweet, and so I did not understand why the friend asked me which sweet or salty is. Then, another friend taught me the words "Savory pie" which indicates any salty pie. So, I was surprised that pie indicates the texture but not any taste type. That was very interesting.
