Modern Hebrew is the primary official language of the State of Israel. As of 2013, there are about 9 million Hebrew speakers worldwide, of whom 7 million speak it fluently. Currently, 90% of Israeli Jews are proficient in Hebrew, and 70% are highly proficient. Some 60% of Israeli Arabs are also proficient in Hebrew, and 30% report having a higher proficiency in Hebrew than in Arabic. In total, about 53% of the Israeli population speaks Hebrew as a native language, while most of the rest speak it fluently. In 2013 Hebrew was the native language of 49% of Israelis over the age of 20, with Russian, Arabic, French, English, Yiddish and Ladino being the native tongues of most of the rest. Some 26% of immigrants from the former Soviet Union and 12% of Arabs reported speaking Hebrew poorly or not at all.

Steps have been taken to keep Hebrew the primary language of use, and to prevent large-scale incorporation of English words into the Hebrew vocabulary. The Academy of the Hebrew Language of the Hebrew University of Jerusalem currently invents about 2,000 new Hebrew words each year for modern words by finding an original Hebrew word that captures the meaning, as an alternative to incorporating more English words into Hebrew vocabulary.

In our visit to Israel in 2019, most signs were in Hebrew, English and Arabic, but English was spoken by everyone on the street. Hebrew was heard at times as people passed on the street.

While Hebrew is an ancient language, there are 3 distinct dialects or versions, the ancient Biblical Hebrew, midieval Hebrew and modern Hebrew which share little common vocabulary.
