מְזֻיָּן (mezuyan) — armed; (slang) screwed, duped

Etymology

The story of מְזֻיָּן is a collision between an ancient military term and a 20th-century Viennese-style gymnasium slang. The noun זַיִן (weapon) entered Aramaic from Old Persian zāēna after King Cyrus conquered the ancient Near East in 539 BCE. Persian was the administrative language of the empire and zāēna naturalized into Aramaic as zayin, generating both a noun and a verb meaning "to arm." Both the noun and verb passed into Rabbinic Hebrew: the Tosefta records "אין מוכרים להן לא זיין ולא כלי זיין" (one may not sell them weapons or weapon equipment, Avoda Zara 2:4).

Rabbinic literature also records, for the first time, the name of the seventh letter of the Hebrew alphabet — זין — possibly named for its resemblance to a weapon. Later, under Arabic influence, the root זי״ן acquired a second meaning in the Babylonian Talmud: beauty and ornamentation (Arabic zayn = beauty, zāna = to decorate). The Talmud uses it to describe the decorative serifs on certain letters: "שבע אותיות צריכות שלושה זיונין" (Menaḥot 29b).

In early 20th-century Hebrew, זִיּוּן (arming/armament) was the standard word for military equipping, appearing routinely in newspaper headlines about wars and nations arming themselves. But meanwhile, students at the Gymnasia Herzliya in Tel Aviv had quietly taken the word זין — perhaps as a shortening of coarser Yiddish slang — and turned it into a vulgar term for the male sexual organ, then derived verbs from it. Engineer Shraga Irmay, who attended the school, documented this in a 1937 letter to the Hebrew Language Committee: לְזַיֵּן meant "to deceive," מְזֻיָּן meant "deceived, a schlemiel," and לְהִזְדַּיֵּן meant "to fail."

These slang meanings spread among the younger generation while adults continued using זיון in its military sense — creating comic double-entendres that Amos Oz famously recalled in A Tale of Love and Darkness, describing a Menachem Begin speech about foreign powers "arming" Israel's enemies that reduced the teenage Oz to uncontrollable laughter.

Gradually, speakers uncomfortable with the double meaning shifted to חִמּוּשׁ (arming) and לְחַמֵּשׁ, derived from חָמוּשׁ in Exodus 13:18. Today מְזֻיָּן survives mainly in its slang sense and a few frozen expressions: "שוד מזויין" (armed robbery) and "בטון מזויין" (reinforced concrete).
