According to a great essay by Pacific Paranormal Investigations, there was a physician, philosopher, and alchemist named Paracelsus that proposed the idea of classifying nature spirits based on the elements they were made of.
Hence the name "elementals," used today to describe nature spirits.
Because of this system of classification, there is not just one "type" of elemental. There are earth elementals, water elementals, fire elementals... basically any type of nature spirit can fall under the "elemental" umbrella term.
Still, it's widely agreed upon by paranormal enthusiasts that elementals are not human spirits. This doesn't mean they're necessarily "evil" or "bad"... they're just not human.
Looking back on our own investigations, I wonder:
Was the entity that pushed and scratched an investigator at the haunted Rosevear Park woods an elemental?
Was the entity that psychic-medium Cat Ryan said was "hunting" the living at the Priggooris Park woods an elemental?
Was the entity that wanted us to "die," suggesting we "fall off the bridge" at the Rotary Park woods an elemental?
