The spelling of the word "most kneehigh" may seem unusual. However, the pronunciation can be explained using the International Phonetic Alphabet (IPA). The word is pronounced as /moʊst niːhaɪ/, with the emphasis on the first syllable. The "knee" and "high" sounds are combined into one, represented by the "ni" in the IPA transcription. This word is typically used to describe something that is almost or nearly knee-high, such as most kneehigh grass or plants.
