Another word that changes pronunciation depending on its part of speech: record. When used as a noun, the first syllable is stressed, but when used as a verb, the second syllable is stressed. Also, the pronunciation of the vowel in the second syllable is very different. More so than in a permit/permit, proceed/proceed, or attribute/attribute pairing.
I took another final today, and when I turned it in, I told my professor, "Here's your answer key right here." She thought that was pretty funny. I wonder if that means she doesn't think I know the answers.
