The word "canum" is a Latin word that is often misspelled as "canium". The correct spelling is "canum" because the letter "i" in Latin is pronounced as "ee" and the letter "u" is pronounced as "oo", which is represented in the International Phonetic Alphabet (IPA) as /kænum/. This is important to remember especially for those studying Latin or using Latin words as it affects the pronunciation and meaning of the word.
