For a famous example, Umberto Eco's essay "The Ur-Fascist" isn't describing what the first or original fascist movement was, but instead exploring what makes Fascism Fascism. This usage seems to be pretty consistent across academia, who engage in the vast majority of cases of slapping foreign prefixes onto English words.
> You can learn all the important parts of array-oriented programming with J and use actual words to do it.
J doesn't use actual words. It uses symbols just like APL. In fact, APL uses proper words or abbreviations for utilities things that are not part of the core language, whereas J just uses numeric codes combined with more glyphs. However, J is ASCII-only (and uses bi- and even tri-glyphs) where APL uses pleasant and mnemonic Unicode single glyphs, so you don't need to parse which adjacent ASCII symbols form a "word".
avg =: +/%#
&.> is predefined as 'each'.
Same for APL, but the idea is to learn what the symbols mean, so you can keep it concise and think in composing functions and not reading pages of text. Sort of like mathematicians and mathematical symbols.
I program in J and APL, but I have taken to BQN lately. It is the best of both with some additions too.
Algol -> C. Mostly because you can actually do things with C, and yet it remains a fairly small language that's a relatively pure exemplar of the Algol tradition.
Lisp -> Scheme. Also because it's a tiny language that tries to push the fundamentals of the Lisp family (code-as-data, recursion, functional programming, macros) as far as possible.
ML -> Haskell. ML is eager, Haskell is lazy. If you're going to learn about the ML family, you might as well learn the concept of lazyness, which results in a very different style of programming than FP of the Scheme variety (in the Lisp family).
APL -> J. The usage of special symbols is largely irrelevant to the concepts in APL, and it's a barrier to accessibility. You can learn all the important parts of array-oriented programming with J and use actual words to do it.
Self, Forth, and Prolog I would keep as exemplars of their type. I would also add TCL as another ur-language for string-based scripting languages (with Perl, PHP, and SNOBOL as other representatives of the category).
