This past Sunday, my pastor used this word in his sermon. I was horrified to find that I have been pronouncing this word incorrectly! I put the emphasis on the first syllable as opposed to the second syllable; and, gave it a short 'i', as opposed to a long 'i'.
So, when you refer to the remnants of something, like used children's toys bound for the dumpster, you will be able to tell your kids to put the detritus in the garbage.
