The word "KEO" is a fairly short and simple term that may not immediately reveal its correct spelling upon first hearing it. However, with a bit of knowledge about the International Phonetic Alphabet (IPA), it becomes clear that "KEO" is spelled as /kiːoʊ/. This is because the "K" sound is represented as /k/, the "E" sound is represented as /iː/, and the "O" sound is represented as /oʊ/. By understanding the IPA, spelling the word "KEO" becomes straightforward and easy to remember.
