1285: Committee of the Hebrew Language Jun 17, 2018

Unlike French, which has the Académie Française to regular French, Hebrew did actually need a committee to figure out how certain terms would be used. This is because it was merely a literary language for over 1,600 years, and in that time, societies had developed new ideas and new objects which needed to be added to the language. The creator of Modern Hebrew, Ben-Yehuda, order the establishment of the Committee of the Hebrew Language with the specific goal of modernizing where necessary, but he insisted that the gaps be filled, both grammatically and lexically, following Semitic systems, often taking from Aramaic or usually Arabic in order to maintain a predominantly Semitic character. As a point of information, this is not the same reason why certain words changed from Biblical to Modern Hebrew, such as 'anochi' to 'ani' meaning the pronoun 'I'.
