These are definitions of terms that I use frequently in my writing, provided for your convenience and reference. I have generally written all of these definitions myself, but have drawn some of the ideas in some of the definitions from Julia Bascom, Adam Gluntz, and Shain Neumeier. If a term is missing that you think ought to be defined here, feel free to shoot me an email. (Contact information is in the sidebar.)

Some of these definitions derive from disability theory, whereas others address broader sociological theory and critical pedagogy, and others concern disability politics and policy. If you use these definitions, please cite them. I have taken many of these definitions from the body text of formal papers that I have written.

Under construction. Missing terms that should be here.

  1. I see the term douchebag is suggested as an alternative to ableist language, but d-bag is sexist!! It's sexist because it uses a term associated with women to demean and objectify others, as if women are a low form of life. Could you please remove the term d-bag? Thank you!!

    1. The thing about douchebags is that women don't need them. Think about it: vaginas are beautiful, self-cleaning genitalia. What genius fooled us into thinking we needed to pump caustic chemicals up in there? Consider what douches do to things like pH balance and native microbes -- basically, a douche/bag is an invader that disrupts our natural functioning for no discernible reason other than "someone else is going to think I stiiiiiink!" So why on earth would it demean us to call someone that?

  2. We should just go back to using they/them/their rather than xe/xim/xir. Xe/xim/xir is just confusing, and they/them/their were the original gender-neutral pronouns.

  3. Lydia,
    I absolutely love your blog. What a fantastic idea; to provide a key to frequently used terms that you employ in your writing. I wish all bloggers were so preemptive. Can't wait to read more!

Hi! Thank you for sharing your thoughts with me. I manually approve comments, so sometimes it takes a few weeks, months, or even years to find and approve comments. This delay is normal. (Note that I also don't publish every comment, since this is my personal blog.) Unfortunately, anonymous commenting isn't available anymore since it resulted in over one million spam comments in a short period.
