crasis

1. Crasis, mixture, means in rhetoric precisely the blending or mixing together of two vowels belonging to two different words that come into contact with each other, the first of which words ends with a vowel, and the second begins with a vowel; attended at times with a change of at least one of the two vowels for some other vowel, as "th'oar" for the oar; "in't" for into it. (Macbeth)

1. So memorable a thing is End-cut, or Apocope, that it inweaves its eloquent self with two of our dearest names,never-to-be-forgotten personal acquaintances,Sam Weller and Sam Slick, from the latter of whom we cull one sample:

"That 'ere man, Sam Patch, was a great diver," says the Clockmaker, "and the last dive he took was off the falls of Niagara, and he was never heerd of agin till t'other (Crasis, observe) day, when Captain Wentworth, of the SusyAnn whaler, saw him in the South Sea. "Why," says Captain Enoch to him-" why, Sam, how in airth did you git here? I thought you was drowned at the Canadian lines ?"-" Why," says Sam, " I didn't get on earth here at all, but I came right through it. In that ere Niagara dive, I went so deep, I thought it was just as short to come up t'other so out I came in these parts. If I don't take the shine off the sea-serpent when I back to Boston, then my name's not Sam Patch." (Macbeth)

1. The cutting away the front of "and," so that it gets dwarfed into 'n, is a good case of the rare figure crasis, the word before "and" ending with a vowel. (Macbeth)
