The spelling of the word "kurth" can be a bit tricky due to its orthography. The IPA phonetic transcription for "kurth" is /kɜːθ/. This means that it is pronounced with an open-mid, back unrounded vowel sound for the "u" and a voiceless dental fricative sound for the "th." To remember the spelling of this uncommonly used word, you can associate it with similar-sounding words like "earth" or "worth," but with a "k" sound at the beginning.
