When one responds, "Amen Yeheh Shemeh Rabba" to Kaddish, he must ensure to pause between "Amen" and "Yeheh Shemeh Rabba." The word "Amen" is a response to the prayer that the Hazzan had just said – that G-d's Name should be glorified and praised throughout the world. The words "Yeheh Shemeh Rabba…" constitute a separate proclamation, and are not a direct continuation of the "Amen" response. Therefore, one must pause briefly after responding "Amen," before declaring, "Yeheh Shemeh Rabba…"
