Late Vocabulary
I came to a lot of this language late.
Not because it didn’t exist — it did, somewhere — but because the conditions that would have sent me looking for it didn’t arrive until recently. A daughter’s offhand observation. An essay that described something I’d spent years calling a personality trait. A word that fit something I’d only ever called the way I am.
This is a running glossary. I add a term when I encounter one that names something I already knew but didn’t have language for. The format is simple: what the field means by it, and what I mean by it. Those two things are sometimes the same and sometimes not.
I’m not an authority on any of this. I’m someone learning new words for old experiences, which is its own kind of strange.
Autistic Burnout
Chronic exhaustion resulting from sustained masking and navigating a neurotypical world without adequate support. Distinct from ordinary burnout — it accumulates slowly, often invisibly, and can take months to recover from. Characterized by a significant reduction in functioning, increased sensory sensitivity, and loss of previously held skills.
Not a bad week. Not the kind of tired a long weekend fixes. This is what happens when the coping systems that have been running quietly in the background — for years, maybe decades — finally run out of capacity. What’s left is the thing they were compensating for, with nothing left to manage it. The scaffolding didn’t fail. It just hit its limit.
Autistic Shutdown
A stress response in which the nervous system effectively goes offline — communication reduces, movement slows, social engagement becomes inaccessible. An inward withdrawal rather than an outward expression. The system protecting itself by becoming unreachable.
This is the one that gets misread as a mood. As withdrawal. As some kind of verdict being issued about the room or the people in it. The system isn’t gone — it’s just locked from the inside for a while. I’m still there. I’m just not available.
Masking
The conscious or unconscious suppression of neurodivergent traits to appear neurotypical — adapting behavior, speech, or emotional expression to fit the expectations of a given environment.
I spent a long time calling this being professional, or being good in a room, or knowing how to read people. I was not wrong. Those things are also true. What I didn’t know was the cost — only that by evening, something was gone.
