The word SDMISS may seem like a bit of a mystery, but when broken down phonetically using IPA transcription, its spelling becomes much clearer. The first two letters, SD, are pronounced as an initial /s/ and /d/ blend, similar to the "st" sound in "stop." The next three letters, MISS, are pronounced as a simple /mɪs/ sound, like the word "miss" without the "t." Therefore, the correct spelling and pronunciation of this word is "SDMISS" (/sdiːmɪs/).
