The terminology around "narcissism, grandiosity and pathological lying" can be quite confusing.  One can have each of them in "pure" form, or in a combination. 

The classification here is not academic or  exhaustive :  in this "Therapist Uncensored" podcast, there´s a more elaborate analysis.   

Watch out for the warning at the bottom: of you have the combination of all these as a relationship, immediately see help with a therapist.
