The Hebrew alphabet or aleph-bet (Hebrew: אָלֶף־בֵּית עִבְרִי, Alefbet ivri), known variously by scholars as the Ktav Ashuri, Jewish script, square script and block script, is a unicameral abjad script used in the writing of the Hebrew language. Alphabets based on the Hebrew script are used to write other Jewish languages, most notably Yiddish, Ladino, Judeo-Arabic, and Judeo-Persian. In modern Hebrew, vowels are increasingly introduced. The Hebrew script is used informally in Israel to write Levantine Arabic, especially among Druze. The script is an offshoot of the Imperial Aramaic alphabet, which flourished during the Achaemenid Empire, and which itself derives from the Phoenician alphabet.
