Thinking Our Loud

So to speak...the word "suss" is new to me.  I googled it and learned that it means to figure out. Using my frame of reference then does "suss" mean the same as "discern."  Do you suss out a vocation?

Looking further I found out that the word "suss" comes from "suspect."  Oh!  There you go.  Suss does not mean the same as discern.  But I can suss that you are thinking of a religious vocation.
