Lexical Sets of English

As you all well know[*], there exist dialects of English that preserve vowel distinctions that the majority do not (such as "wait" vs. "weight", or "meet" vs. "meat").

Now, while reading a blog entry on the "Great New Zealand Vowel Shift", I came across an updated version of the standard lexical sets for English, labelled as the Revised Wells/Mills/Cowan/Rosta Really Universal, Dammit, This Time, Lexical Sets, in a comment by the famous John Cowan:

KIT, DRESS, TRAP, BAD, LOT, STRUT, FOOT, BATH, DANCE, CLOTH, NURSE, TERM, DIRT, FLEECE, BEAM, FACE, TRAIL, FREIGHT, PALM, THOUGHT, GOAT, SNOW, GOOSE, THREW, PRICE, CHOICE, MOUTH, NEAR, SQUARE, START, NORTH, FORCE, CURE.

[*] It's a joke, son.
