Could you use that in a sentence?

I think there should be a rule that you cannot not use a word in general conversation that you could not readily spell or at least have spell check suggest as an alternate.

Building on that rule, you should not generate a random pronunciation of the aforementioned word to match your pending misspelling of the word.

This week my ears have witnessed some egregious mispronunciations and ignorant uses of multi-syllabic words. Sounding smart and being smart are two VERY separate things.
