The spelling of the word "prud" is a bit tricky as it doesn't follow the usual conventions of English spelling. The word is pronounced as /prʌd/ which means that it starts with a voiceless bilabial plosive consonant /p/ followed by a mid-central vowel /ʌ/ and ends with a voiced dental fricative consonant /d/. The spelling of the word lacks a vowel letter between "p" and "d", making it phonetically ambiguous. It may be misspelled as "prd" or "prde".
