The word "turpid" is spelled with a "p" rather than a "b", even though it may sound like the latter when spoken. The IPA phonetic transcription of the word is /ˈtɜrpɪd/ which shows that the second letter is a voiceless bilabial plosive sound, rather than a voiced bilabial fricative sound that would be indicated by the letter "b". It is important to note the correct spelling of words to avoid confusion and to ensure effective communication.
The word turpid is derived from the Latin word turpidus, which means dirty, disordered, or disgraceful.
