RDF is a language, thus it is comprised of the following:

1. signs -- for entity denotation (in this case IRIs)
2. syntax -- constructing statements that represents entity 
relationships (in this case subject, predicate, object, triple patterns)
3. semantics -- for understanding the meaning of different types of 
relationships (in this case the meaning of the subject, predicate, and 
object relationship roles).

A language is a framework for encoding and decoding information. This is 
what RDF is all about. 2 out of 3 (above)  isn't RDF it has to be all 
three, since it's a language.

What can make RDF confusing is the fact that you can create RDF document 
content using a variety of notations or so called "concrete syntaxes" 
(N-Triples, Turtle, RDF/XML, JSON-LD, HTML+RDFa, HTML+Microdata etc..).

I hope this helps.
