After I saw the post I had to go look it up because it bothered me too much. Another commenter mentioned clitics; I discovered the same. Clitics are the non-stressed parts appended to host words in contractions. Grammatically, auxiliary verb clitics ('m, 's, 'll, 'ld, 're) are not strong enough to stand on their own at the end of a sentence (this forces too much stress on the clitic); however, the reduced negative "n't" (not) is an exception and grammatically able to stand at the end of a sentence because it becomes an inflection of the verb more than a contraction. Other exceptions include possesive clitics that aren't contractions (someone's, Mike's), "let's" as "let us," and arguably "could've, should've, would've" (pronounced as a syllabic 'ev' instead of simply 'v') where the 've appends to a strong-form verb host that can take the stress. Will this knowledge allow your mind to rest? It willn't.
