Neshaveh (נשוה) is a Jew-exclusive term that is similar to Alterhuman in nature or Altherhumangender. It refers to the state of having a soul, mind, or identity that is nonhuman. This can include alters, otherkin, or alterhuman identities.
Etymology
Neshaveh comes from the word for "equal/same/even souls/spirit," in reference to how in a Jewish belief, humans possess two souls that can act independently or work together.
Notes
In Judaism, there is a teaching that refers to humans as having two souls: One that is human-like, always seeking ascension, enlightenment, knowledge and spiritual evolution, the other that is animal-like and seeks survival, self-serving, materialism, and physical cravings.
It's said that it's possible for someone to 'teach' their animal-soul to turn away from these physical desires and instead seek spiritual enlightenment, or to become equal (but not one with) the human-soul.
Neshaveh refers to this belief loosely as a base for beliefs in people who may identify more or completely with their nonhuman identity over their human form. (This doesn't require the person to follow the spiritual beliefs, but they do need to be religiously Jewish, secular Jewish, or ethnically Jewish to use this term.)
