This is a term we just ran into* that will be a fantastic addition to your vocabulary! “Biotypical” can be used to describe a person without chronic illnesses or disabilities.
This term follows in the tradition of words like “cisgender” and “neurotypical,” which give a label to things most folks consider to be the norm (and might cissexistly or ableistically label as “normal.” This has the effect of putting the two things on even ground linguistically (”trans” is no longer an outlier, but one of an even dichotomy), and gives marginalized folks a word to use about the dominant group, perhaps even pejoratively if they’re feeling feisty >:)
So go forth and reap the benefits of this new word!
*Having done a little research, it seems that two folks simultaneously started using the word around the same time on Twitter, with a similar meaning in mind: @coffeespoonie and @LizyNewswanger (@lizynewswanger-blog here on Tumblr). See our Twitter discussion here.
Going a little farther back: @JuliPilgrim made a mention of it in 2015, but as part of a list containing other “typicals,” rather than its own concrete concept, and we see @ShunraCat using it to make a pun in 2013. However, both of these seemed to be incidental wordplay versus ongoing use of the word.
Don’t get us wrong, biotypical was already a word well before this, and we could be overlooking something. But we did want to put something down for internet posterity. It would be interesting if you know of anyone who’s used it for a long time, so please feel free to comment with what you know!
