Earlier quoted context omitted.
Is there a more intuitive word for "affordances" or similar? I find its definition is always debated or confused in the comments so I prefer to avoid it where possible.
Nope, that's the nomenclature and it means something very specific in the cases of architecture and UX. Affordances "afford" cues to the viewer that something has perceived action possibilities. It's the opposite of a hidden passageway door or a flat rectangle that doesn't have any cues to indicate that it's a button. https://en.wikipedia.org/wiki/Affordance
> The different interpretations of affordances, although closely related, can be a source of confusion in writing and conversation if the intended meaning is not made explicit and if the word is not used consistently. Even authoritative textbooks can be inconsistent in their use of the term.
