The spelling of the word "threatt" is unique, and can be confusing to those unfamiliar with it. The correct phonetic transcription for this word is /θrɛt/, with the "th" sound in "threat" pronounced as a voiceless dental fricative. The double "t" at the end of the word indicates a sudden, forceful ending to the sound. This spelling is common in African American English, where it is used as a surname, but may not be as recognizable to those outside of that community.
