The word "starchness" is spelled with the consonant cluster "ch" followed by the consonant "n". The IPA phonetic transcription of this cluster is /tʃn/, which represents the sound made when the tongue moves quickly from the /tʃ/ (as in "chap") to the /n/ (as in "no"). This sequence of sounds may seem odd to some speakers, as it is not common in English. "Starchness" refers to the quality of having or being full of starch, a carbohydrate found in many foods.
