Hello! So, there's a lot of terms in the plural/multiple/system community! Not just on Tumblr, but Twitter and Reddit.
We're trying our best to add as much as we can to this dictionary, for anyone to find. I know we've had trouble finding the meaning of some terms, even searching, so hopefully this will help!
Please go to the Contact page and send us a message in one of the places if we've missed something.

Disclaimer: Not all definitions are written by me, I tried to make sure everything made sense, and sometimes we aren't good at putting thoughts on paper.

All flags are above their definition.

4/6/2020: Posted, missing Member Type flags, and some System Type flags.

4/7/2020: Added another DID flag, added the remaining Member Jobs, added a few alternate names to some terms, and added some missing basic terms.

4/13/2020: Added a few terms [Parethnic, Spontagenic], added separators between flags so you can easily tell which flag goes to which definition. Added Tools section, under More.

4/19/2020: Added links to Tumblr posts for newer terms, so you can reblog and spread them. Follow the ♡'s to find the posts. Will add links for more known terms at a later date. Added relationship terms under More.

5/21/2020: Really big update.
