The word Nomenclature comes from Nomenclator, who is a person who calls out names. "Nomen" means names and "clator" is a person who calls out.  When students get their diploma, the nomenclator is the person who calls out the students' names.  In chemistry, "nomenclature" is learning to call out chemical names.   Understanding chemistry nomenclature is like learning any language.  It takes practice and study, but the reward is that it gives you the ability to talk to people you couldn't talk to before.
 

 33. 
What does the term nomenclature mean?
a.
learning to call out chemical names
c.
to mold from clay
b.
writing formulas
d.
to practice and study
