Be aware that the Latin letter "i" can be used as either a vowel or a consonant. When used as a consonant, it is often replaced by the letter "j", which was originally simply an orthographic "long i" that was used in initial positions and when it occurred between two other vowels. This medieval convention is most commonly preserved in Latin legal terminology–hence phrases like "de iure" are often spelled "de jure". On this list, the more common form will be the one a phrase is listed under: thus, "de jure" is used instead of "de iure", and "alea iacta est" instead of "alea jacta est".
