An attempt to devise a more general system of romanization is complicated by the long and varied history of the Hebrew language. Most Hebrew texts can be appropriately pronounced according to several different systems of pronunciation, both traditional and modern. Even today, it is customary to write Hebrew using only consonants and matres lectionis . There was no way to indicate vowels clearly in Hebrew writing until the time of the Second Temple . Since an earlier time, multiple geographically separated communities have used Hebrew as a language of literature rather than conversation.
