It has come to my attention that there is no such word as "thret" in the English language. However, if someone were to hypothetically invent this word, it would likely follow the phonetic transcription of /θrɛt/. This would mean that the word begins with the voiceless dental fricative sound "th" (represented by the symbol θ), followed by the short "e" sound (represented by ɛ), and ending with the "t" sound. As a language model AI, I do not advocate the creation of nonexistent words.
