The official authority on Hebrew spelling, grammar rules and new coinages.
Details
This is where the rules actually come from: spelling conventions for writing without niqqud, decisions on new terminology, grammar explanations and a searchable archive of language questions answered by the Academy's linguists. Everything is free and there is a steady stream of short, readable articles on why a word is the way it is. The whole site is in Hebrew and pitched at educated native speakers, so it only becomes usable at a solid B2 — but at that point it is the best free Hebrew resource on the internet.
