Incidences 

Incidences is a hybrid word (instances and incidents) that attempts to add importance and intellectual heft to a person's otherwise dull pronouncement. You hear this word all the time especially on newscasts where the host tries to sound important by using a bigger word than necessary.

" The incidences of credit card theft have risen dramatically since the influx of immigrants from Upper Freedonia have entered the neighborhood once know as Little Albania."
