Add the prefix De, which means; from or of.
You get denominate to name those coming out from
Add the suffix Al which means something like; act of
So you get some thing like the naming of those who come out from.
In a large group you will have those who come out from the one group and form another group or a denomination, and they will rename themselves something related.
I hope that helps a little.
Maybe I'm not real got at explaining that stuff
