&gt; except the &quot;in other words&quot; section which links it to other (linked) structures.<p>That&#x27;s what I was getting at. I took a few classes in AA and its sibling topology, including at graduate level. Most of the time was spent defining things, because there&#x27;s so many terms with very specific definitions. Only after maybe 2&#x2F;3rds of a course do you really start getting into deeper material. In my brain, reading definitions was always a process like: read through, substitute definitions for jargon terms, read through, substitute... iterate until you hit a fixed point.<p>That&#x27;s standard for math, but AA is particularly well known for its colorful choice of names. Some people enjoy it, but I was always more attracted to the analysis-family areas of math.<p>I&#x27;ve always found the other name for category theory amusing though: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Abstract_nonsense" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Abstract_nonsense</a>
