The spelling of the word "sandu" may initially confuse readers, as it seems to lack a cohesive phonetic pattern. However, using IPA phonetic transcription, we can break down the pronunciation: /sændu/. The "s" sound is followed by a short "a" sound and a nasalized "n," and the word concludes with a "d" sound and a short "u." The seemingly random combination of English letters can be explained through its origins in other languages or dialects. As always, pronunciation is key to understanding and effectively communicating written words.
