What was peter name in aramaic?

The Aramaic name for Peter is Kēp̄ā (pronounced "Kay-fa"). This name translates directly to "stone" or "rock" in Aramaic, which is the same meaning as the Greek name "Petros" (the name Jesus gave him).

It's important to remember that the Aramaic language was the common language of Jesus and his disciples, so Kēp̄ā is the most accurate representation of Peter's name in the language he would have spoken.
