The spelling of "dies soils" is rather unusual, and it can cause confusion for those who aren't familiar with its pronunciation. The word is pronounced /daɪz sɔɪlz/, with the first syllable rhyming with "eyes" and the second syllable sounding like "soils" with a soft "s" sound. The word means that something spoils or tarnishes over time, such as a material or a reputation. It's important to note that the correct spelling of the word uses an "s" at the end of each syllable, not a "z."
