Words you didn't know how to say or spell

[zachary_amaryllis]

louisville, co != louisville, ky
saguache = 'sa-watch' (i think)

gloucester != 'glou-cester' but 'glaw-ster'
worcester != 'wor-cester' but 'wooster'

[Tom958]

Jewelry.  It's not jewel-ah-ree. Only two syllables (my great aunt always corrected people till her dying day)

Correct, but the British and presumably others use "jewellery," the stuff that jewelers produce, instead of "jewelry," jewels and their accouterments. The mispronunciation is likely a relic of that.   

Plus, jew-el-ry has three syllables.
