צַדִּיק (tsaddik) — the eighteenth letter of the Hebrew alphabet

Etymology

The eighteenth letter of the Hebrew alphabet was originally called צָדִי, as attested in the Babylonian Talmud, Tractate Shabbat (104a): "צד"י כפופה וצד"י פשוטה צדיק כפוף צדיק פשוט." This passage discusses the two written forms of the letter: the "straight tsadi" (what we call צדיק סופית, the final form) and the "bent tsadi" (the standard internal form). Interestingly, the final form (ץ) is actually the older shape, while the standard internal form evolved from rapid cursive writing.

The name צַדִּיק — the form used today — appears in manuscript sources from medieval Europe. The most likely explanation is a process of "consonantal absorption": the first consonant of the following letter's name, קוֹף (the letter ק), attached itself to the end of צָדִי, producing צָדִי-ק and eventually צַדִּיק. It is also possible that the same Talmudic passage, which describes the letter using the word צַדִּיק ("righteous man") in a homiletic context, contributed to cementing this name. The form צַדִּיק was standardized in Yiddish and eventually passed into Modern Hebrew.

The article's broader subject is the phonology of the consonant this letter represents. In Ashkenazi tradition (and Yiddish), the letter is pronounced ts (like German z or Russian ц). In Sephardic and Yemenite tradition, it was pronounced as a pharyngealized (emphatic) consonant, similar to Arabic ṣ. Linguists long assumed the Sephardic pronunciation was original and the Ashkenazi ts a European adaptation, but more recent scholarship argues the ts pronunciation may in fact be original, pointing to early rabbinic transliterations and noting that Cyril — inventor of the Cyrillic alphabet — used the Hebrew tsadi as the model for his Ц (= ts).

Comparative Semitic linguistics reveals that the Hebrew letter צ actually represents three historically distinct consonants that merged before the invention of the alphabet. These three types are visible in cognate comparisons: the tsadi of צֶדֶק / צֶמַח (corresponds to Arabic ṣ), the tsadi of צְבִי (whose Arabic cognate is written with a different letter, originally pronounced as a voiced emphatic interdental), and the tsadi of אֶרֶץ (whose Aramaic cognate showed various mergers — with ק in early Aramaic, with ע in later Aramaic).
