The word "Zer" is a bit tricky when it comes to spelling because it doesn't follow typical English pronunciation rules. The correct way to spell it using IPA phonetic transcription is /zɛr/. This means that the "e" is pronounced like the short "e" sound in "red," while the "r" at the end is pronounced as a soft, non-rolled sound. Although the spelling may seem unusual, it's important to remember to use proper IPA transcription to accurately capture the sound of words when speaking or writing.
