The spelling of the word "Highred" may seem odd, but it is actually a phonetic representation of the word "hired". The symbol /aɪ/ represents the long "i" sound, while the symbol /r/ represents the "r" sound. The letter "d" at the end of the word indicates the past tense. While this may not be a commonly used spelling, it can be useful in teaching basic phonetics or in representing certain dialects or accents.
