The phenomenon, from my 8/25 posting “Exception-triggered alternation”, involves:
Two contrarily opposed states — good vs. bad [in a joke routine], forestressed vs. afterstressed [in the accentuation of N + N compounds] — for some phenomenon, with the choice between them determined by context, the choice flipping between the two as the context narrows more and more (with each flip, the contextually more specific choice overrides the contextually more general one).
“More specific overrides more general” is a familiar principle, known by many names; what the statement above emphasizes is that this overriding can cascade, through a number of iterations.
Now, as an addition to these two examples Larry Horn (Laurence Horn of Yale Univ.) offers another, from formal semantics: Sobel sequences. Here I’ll turn the floor over to Larry, for a guest posting on them. As background, the cover of David Lewis’s Counterfactuals book (in the paperback edition, much more visually exciting than the severe cover of the edition I once had):
In Larry’s words, from here on out:
