People often find it difficult to intuit examples from abstract descriptions. BUT, people are great at intuiting abstractions from concrete examples.
You rarely need to explicitly mention abstractions, in informal talk. People's minds are always abstracting.
> If I’m relating the collections {cat} and {at-cay}, that’s a standard “Pig Latin” transformation I can manage with a simple, handwritten rule set.
Or...
"Translating {cat} to {at-cay}, can be managed with one “Pig Latin” rule:
If input is {cat} then output is {at-cay}."
"Translate" is normie and more context specific to the example than "transformation". "Set" is not "normie" (normies say "collection"), and its superfluous for one rule.Concrete, specific, colloquial, shorter, even when less formally correct, all reduce mental friction.
