The spelling of the word "more twelfth" may seem confusing, but it is actually quite simple. The first part, "more," is spelled phonetically as /mɔr/. The second part, "twelfth," is spelled as /twɛlfθ/. The tricky part is the "th" sound at the end, which is spelled as "th" and not "thh." This is because the "th" sound is a dental fricative, meaning that it is made by pressing the tongue against the teeth, while the "h" sound is a glottal fricative, made by squeezing the air through the vocal cords.
